I created a survey as a related table to an existing point feature class and am using Collector and custom URLs to populate fields within the survey. However, now the department using the survey would like a couple new questions added so that they can track which surveys they have audited for data accuracy & training purposes. Is it possible to add new fields to the existing feature service? Would I use the admin page and 'Update Definition' to modify the JSON to add the new fields so I can add the new questions to the survey?
