When you create a form, you can mark mandatory fields that must be filled in order to submit a form.
I would like to have the same possible for update requests - that a submission only is possible if all required fields are filled. Today you can submit an update without changing anything, which is fine for some workflows, but for other where you do this to gather information, it would help to have the possibility to mark what always must be filled. Today we have to retrigger the workflow to get the update corrected.
