How to programmatically change folder and group membership? I need to be able to bulk-create items in a specific "folder" (not root) and at the same time, change group membership of those items. I'm using GitHub - Esri/ArcREST: python package for REST API (AGS, AGOL, webmap JSON, etc..) to create the items, which, unfortunately, does not allow for folder and group manipulation. Surely someone has figured this out with Python....?
