Can we get a better system for Questionnaires and how they are submitted?

I would love the questionnaire to be editable by the client after it’s been submitted. Or at least be able to reopen it for them to edit. This happens regularly: I will send a client a questionnaire and they may not be ready to complete the whole thing. I tell them that it autosaves and they can exit out and wait to submit. However, it is not user friendly because I have clients “accidentally submit the form” regularly (2-5x a month) Then they have to ask me to resend them a new one. This is a huge waste of time and a pain for me and for them especially if they have spent time filling it out partially as I have to copy and paste the answers. I would LOVE the option for the client to go back and edit once it’s submitted or at least be able to reopen it. Or, have the buttons changed to say, “Exit” and another for “Submit” to make it more clear to the client.
