I have a hosted feature class in ArcGIS Online with two related tables. Users view the data through a web app. The feature class contains data equivalent to "Site ID". The users are most interested in the related tables and they download them to csv. Though, once downloaded and the relationship is broken, there isn't an easy way of working out which site ID each record in the related table relates to (I know the Global ID will work but this isn't easy to view/interpret).
Is there a way to append the Site ID to the related table?
