I'm curious how other users are managing use cases like this.

Owner of the process I'm creating wants an approver to be able to click a "Reject" action button on the form to return it to an earlier stage in the process.  But they want to do it without filling in a dozen required fields on the form (basically make them required when submitting but not when rejecting).

I know I could do this with Field rules and a checkbox/radio button/etc. to make the decision - but they really want it to be with the submission buttons.

I handled this on the Classic Designer by having Javascript remove the required attribute from the fields when the Reject button was clicked, and they are wanting that same functionality in the Layout Designer.

Any suggestions or tricks that people have learned to make this kind of thing work in the Layout Designer?
