Allow users to save groups of fields as reusable field sets

It would be helpful if users could group multiple commonly used fields together and save them as a reusable field set or custom button.

For example, I frequently add the same four fields to agreements:

• Signature
• Name
• Title
• Date Signed

Rather than dragging and placing each field individually every time, I would like to save these four fields as a “Signature Block” and then drag or insert the entire group onto a document at once. After placement, each field should remain an individual element that can be moved, resized, or otherwise adjusted as needed to accommodate different signature blocks and document layouts.

This would be especially useful for users who send many different agreements where templates are not practical because the underlying documents and signature locations vary.
