If you could explain what you are trying to do that would help because right now a lot of assumptions need to be made to even try and answer this. How do you see this working? Would it save the record automatically so they could come back later if they were afk for ~10 minutes? Things like that.
There is nothing stopping someone from saving an incomplete record right now. If you have things like notifications or automations that fire when a record is added there are things you can do to stop that. The simplest for me is having a checkbox on the form, like "Completed", where the user checks it before saving when the record is fully ready. Then your automations could also look for that box to be checked to know it was finished. There are other ways too that would not require the user to click anything for you to know the record was ready but that depends on your form and how complicated it is probably.
