Add a Parallels Device Collection option in the context menu (in the blank space after Saved Searches at the top) that when you click it a (drop-down) menu appears with options to create Mac Device collections such as all IBCM clients, all MDM clients or all DEP clients, etc. (all it would need to do is create a device collection with a membership query for whatever option was chosen). I have manually created these collections with membership queries but it would be good to add some way to automate this for some relevant-to-every-environment collections.
