Regarding the pulldata function for Survey123 is it possible to use this function on internal data (i.e. sql related tables) to auto-populate surveys other than using external data (csv files)?
An enhancement ENH-000119959 has already been raised for this request similar to yours, although it is currently in our backlog and not a high priority for development in the near term. I would suggest contacting Esri support and attaching your request for this functionality to the existing enhancement request.
