I'm using Portal instead of AGOL but same concept. This layer is coming from another internal system through an eURL so I cannot add fields. Just the fact that I'm able to bring in this data real-time using eURL in its own is a game changer! Especially in Operation Dashboard. Of course, I get the question, "Can we add the average time it takes to complete different tickets?" I have to see if I can do the calculation in the original system first but, so far, I have had no luck.
