It’s unclear to me precisely what this means so I’ll answer in a way that I hope addresses your question. 
You are free to plugs removable-media in any snaps you wish. Plugging the interface does not trigger a manual review and there are no snap declarations needed to use the interface.
For auto-connecting, we don’t grant auto-connect for removable-media since the access is almost always optional and we want to preserve the user’s voice so forum requests are needed where you feel the functionality is required.
If you have just a few that you want to auto-connect, the I suggest filing different topics for each. If you have a lot and several have identical, specific requirements, then we can try out having you create forum topics for each group of applications. Please be sure to read through both “auto-connection request considerations” and “Manual connection mitigations” in Process for aliases, auto-connections and tracks before doing all the legwork with the forum requests. If you have questions about those sections, feel free to ask them here and we can discuss before you submit more forum requests.
