I'm using an ArcGIS Online basemap inside of ArcMap. The sources involved in creating the Agol basemap are listed in the layout, e.g. Esri, HERE, DeLorme, etc. My issue is that most of the data in the map apart from the basemap are data created and managed by my organization. I am unable to modify the Credits field inside of layer properties. I think I've figured out a work around before but can't recreate that solution now since editing is not allowed in the Credits field in properties (though it lets you modify the Description field). Does anyone have any idea how I can modify the "Sources" label on layout in order to include my organization in the credits for data sources?
