It would be awesome to be able to get the members of an ArcGIS Online instance in a hosted table or as a new "Team Member" field option.
Why this would be beneficial? In a number of use cases, items or workflows need to be associated with an individual(s) but getting the values to use in dropdowns or selection options have been challenging requiring the use of python to pull those names and details into a usable form. Instead, what if from the members page, an admin could set up a hosted table of members from the members data that stays updated as members change.
What if that same data could be used within a new "Team Member" or "Viewer" field type that could be filtered based on attributes. This would require a bit of expansion on the team members details so that information such as department, office/location, role, etc. but would be a powerful addition to the ArcGIS Online platform.
We currently have to sync this sort of information from an Airtable instance where were leverage a pulldata function to create the necessary dropdown options for Survey123. The above would save so much time and effort for our team and we are less than 300. For larger orgs, this could be a tremendous time saver.
