Hi! I am by no means a Survey123 expert but I was able to accomplish this in my feature report template following the docs here: https://doc.arcgis.com/en/survey123/browser/analyze-results/featurereporttemplates.htm
In my case, I had user input data from a repeat question representing multiple watersheds related to a single point feature. In my feature report template Word document, I created a table like so:
HUC | Name | Total Acres | Acres Burned | Percent Burned |
${#WatershedFire} ${HUC} | ${ Name} | ${TotalAcres} | ${AcresBurned} | =${PctBurned} ${/WatershedFire} |
In this example, my related table is called WatershedFire and the fields (HUC, Name, TotalAcres, etc.). Note the syntax for opening and closing. When I generate a feature report, all the related records are added automagically and I get a table with multiple watersheds.
I hope this helps!
