In web maps or web app builder it would be awesome if users could set up triggers to auto calculate fields with concatenation of two fields. If we have two fields for example pole class and pole height it would be nice if I could create a field called pole class and height and automatically populate it by concatenating the two fields with a dash between the two instead of manually calculating this every so often. I hope there is a way to add this to the system as it will greatly improve functionality of web maps and applications on ARCGIS Online.
