You couldn't do it with only "out-of-the-box" functionality, however, you could use a little bit of javascript to supplement the built-in functionality provided by field rules.

For example, you could add a hidden field with no default value, then add an event handler to your link that populates that field with a value when the link is clicked. Set your Field Rule to show your other field when that "tracking" field is not empty.

$(document).ready(function(){
    $('#myLink').on('click',function(){
        $('#Field100').val('clicked').change();
    });
});

Assuming you're using custom HTML for your link, just add an ID attribute and replace "myLink" with whatever you use as the ID, and replace Field100 with the ID for your "tracking" field.

Your "declaration/confirmation" field can be whatever type you want, just set a field rule to show it when your hidden "tracking" field is Not Empty.
