I have a way to do it on the classic designer with Javascript.

This is tested on Forms 11 Update 2.

On your form, enable pagination.  Make sure there is at least a first and last page.  Then add as many pages as you want in between those pages.  Here's an example with a maximum possible of 25.  You can name the pages whatever you want:

There needs to be a limit because you have to add a page for each possible record.  But all you are doing is adding the pages, you are not putting anything on the pages, so you can easily add quite a lot of them if needed.  Important: Make sure the number on line 64 of the Javascript below is matching the number of pages - because my example has 25 page, the line of Javascript says 25.  The line will help ensure rows are not added to the collection that don't have pages set-up for them.

On the First page (I named mine "Start"):

• Add a number field.  I named mine "Number of Records".  Leave it Do not make it read-only.  Give it these two CSS Class Names:   javascriptReadOnly recordCount
• Add your collection.  Give it the CSS Class Name of:   pagesCollection
• Add as many fields as needed to your collection.  Give one of the fields (only one) the CSS Class Name of:   recordCounter

Add this CSS to your form: 

/*Hide the option to delete rows from the collection because the code
to move them to different pages isn't set-up to handle deletions*/
.cf-collection-delete { display: none!important; }

/*Hide the Collection Title*/
.pagesCollection h2, .cf-section-header { display: none!important; }

/*Hide the border at the bottom of each collection row, otherwise
they are left behind on the first page*/
hr.end_set { display: none!important; }

Add this Javascript to your form: 

$(document).ready(function () {
  
  //Make the javascriptReadOnly fieldsread-only - this has to be done 
  //via Javascript, otherwise the field values cannot be populated 
  //via Javascript.
  $('.javascriptReadOnly input').each(function() { 
    $(this).attr('readonly', 'true');
    $(this).removeClass('hasDatepicker');
    $(this).parent().find('.ui-datepicker-trigger').hide();
  });
  $('.javascriptReadOnly select').each(function() { 
    $(this).attr('readonly', 'true');
  });
  $('.javascriptReadOnly textarea').each(function() { 
    $(this).attr('readonly', 'true');
  });
  
  //When the form first loads - hide all of the pages except 
  //the first and last ones.  They will be shown later as needed.
  //This mimics the way the items are hidden via the Field Rules.
  HideAllPages();
  function HideAllPages() {
    //Version of the code for the active form:
    if($('.recordCount input').val() != undefined) {
      $('.cf-page:not(:first):not(:last)').each(function() {
        var pageID = $(this).attr('id');
        $('.cf-pagination-tabs li[page=' + pageID + ']').addClass('hidden').attr('aria-hidden', 'true');
        $('.cf-page[id=' + pageID + ']').addClass('hidden lf-container-hidden').attr('aria-hidden', 'true');
      });
    }
    //Version of the code for the read-only form:
    else {
      $('.cf-page-readonly:not(:first):not(:last)').each(function() {
        var pageID = $(this).attr('id');
        $('.cf-page-readonly[id=' + pageID + ']').addClass('hidden lf-container-hidden');
      });
    }
  }
  
  //When the form first loads, and when new rows are added to the collection,
  //cycle through each row and move it to a new page and unhide that page.
  //Additionally, the count of records is updated.
  MoveCollectionToPage();
  $('.pagesCollection .cf-collection-append').click(MoveCollectionToPage);
  function MoveCollectionToPage() {
    //Version of the code for the active form:
    if($('.recordCount input').val() != undefined) {
      $('.pagesCollection .rpx').each(function() {
        $('.cf-page.hidden:first').each(function() {
          var pageID = $(this).attr('id');
          $('.cf-pagination-tabs li[page=' + pageID + ']').removeClass('hidden').removeAttr('aria-hidden');
          $('.cf-page[id=' + pageID + ']').removeClass('hidden lf-container-hidden').removeAttr('aria-hidden');
          $('.pagesCollection .rpx:first').each(function() {
            $('.cf-page[id=' + pageID + '] .cf-pagination-btn').before($(this));
          });
        });
      });
      var numberOfRecords = 0;
      $('.recordCounter').each(function() {
        numberOfRecords++;
      });
      $('.recordCount input').val(numberOfRecords);
      //Hide the option to add more records if the count is at least 25
      if(numberOfRecords >= 25) {
        $('.pagesCollection .cf-collection-append').hide();
      }
    }
    //Version of the code for the read-only form:
    else {
      $('.pagesCollection .rpx').each(function() {
        $('.cf-page-readonly.hidden:first').each(function() {
          var pageID = $(this).attr('id');
          $('.cf-page-readonly[id=' + pageID + ']').removeClass('hidden lf-container-hidden');
          $('.pagesCollection .rpx:first').each(function() {
            $('.cf-page-readonly[id=' + pageID + '] h2').after($(this));
          });
        });
      });
    }
  }
  
});
