I have studied this question and found it helpful: How do I edit the response of a form submission in Google Forms/Sheets?
Now I would like to take it a step further. Once I have the editable response URL, I notice that when I go to the URL and edit and submit the response, it modifies the original response line in the sheet.
What if, instead of modifying, I want to make a NEW response. That is, upon editing, when I Submit, the set of responses makes a NEW row in the spreadsheet. I'm trying to think of a way I can do this, but not coming up with anything. Any ideas?
