Hi! I'm wondering the survey workflow described below can work.
One group of field workers goes out and knocks on doors, asking residents if they'd like to have water sampling done. If so, they collect the resident and address info in a survey form.
At a later date, field workers (who may or may not be the same as in the first group) then go out and conduct the sampling, using the remaining fields on the original survey. So, one survey form with one section filled out at one date, and another section completed at a later date.
I can think of other ways, such as one form to collect resident/address info, then some backend process to put that data into a second survey. But if the first way can work, it can save that work on the backend. Thanks!
