ArcGIS Help (10.2, 10.2.1, and 10.2.2)
Tools · Esri/ago-admin-wiki Wiki · GitHub
EsriUK/PythonAGOLTools · GitHub
Using Python to update web mapping applications hosted on Amazon Web Services | ArcGIS Blog
Updating ArcGIS.com Hosted Feature Services with Python | ArcGIS Blog
Nope, I had checked those and neither of those resources provide methods to do that. But thank you for your response, Xander. Any ideas are much appreciated.
