I love the functionality with the custom report templates for survey123. One problem that I have run into is trying to get separate entries within a repeat to report in chronological order, not database OID order. We have staff input data throughout the day, but sometimes they don't enter something until after other entries. They record the time that the first event happened, so the events appear in the order they were entered when reports are printed. It would be nice to have the records appear in chronological order to reduce confusion with the forms.
Currently there isn't method to set a sorting order for repeats in the feature report service. This would be great to submit to ArcGIS Ideas | GeoNet, The Esri Community | GIS and Geospatial Professional Community to keep track of user interest in this and what scenarios they would need to limit display under.
