For really long forms: Add multiple submit buttons for one form

Some of my forms are quite long. The form fields are contingent on user entries (using display rules), so I can't chop the forms up into multiple forms in one view.

Can you add a feature where I can insert submit buttons in multiple places on one form similar to how we can add groups and fields in forms?

We won't be adding multiple submit buttons to a single form - that goes against what's become the standard experience of having a single submit button at the bottom of the form. A better approach may be to break up the form into multiple pages, similar to how this quiz app works:

One of the submit rules you can add (in the Form Rules tab) is to redirect to a child-page where you can continue to edit the record with forms.
