Iterating feature updates with survey results

[MorganJenkins2]

Hello All. I am new to model builder and have hit a wall. I am trying to create a workflow that will update all the features in a feature dataset by deleting the rows and appending updated data tables from survey123. Each feature has its own survey data. I've attached an image of the basic model I built which works for 1 feature and 1 survey, but id like to expand this to work intelligently for many features and many surveys. Please let me know if you need any clarification, I hope this makes sense.

There are "iterators" which can be used in modelbuilder, for example:

Iterate Feature Classes (ModelBuilder)—ArcGIS Pro | Documentation

look at the other examples to see if they might be useful

Hi Dan. Thanks for the response! I did look into this and I believe that will work for the feature class selection. However, once I add 1 iterator I can't add another (for the surveys) and Im not sure how i would make sure the correct survey table updates the associated feature.

I suspect that leaves using sub-models or skipping modelbuilder altogether and rolling out the process as a python script
