Event-based workflow

I'd like to start automatically sending survey responses to a Google Sheet, and it seems workflows are the easiest way of doing so.

While building the workflow, I found I have to map every single field I want (which in my case is every single field, hundreds total) to an appropriate column in Sheets. While time-consuming, this is feasible.
However, my issue is that I duplicate the survey every month to send to different people. I assumed copying the workflow would assist with this, but once I changed what survey triggered it, all the subsequent tasks, including mapping, were deleted (I was warned about this).
Is there not a way to keep tasks the same but have different surveys as the trigger?
