Custom apps should behave the same way as Shared apps - allowing multiple versions to be uploaded and to have those versions displayed in a drop-down under a single app name under Assignment.

Ideally SimpleMDM’s logic for displaying the custom app would follow what’s already in place for shared apps (which is great btw) specifically:
• only 1 instance of the app is displayed in the Catalog by bundle ID or..?
• the ability to select a specific version of the app in the assignment group
