Force specific systems to be always visible
Some of my systems' roms are in external storage. When the external storage is not connected, Dig will remove those systems from view and this is fine. The problem is that when I reconnect the external storage, Dig might fail to recognize this automatically. In this case I have to manually show all systems and browse the ones that have their roms in the external storage.
Since the external storage is frequently connected/disconnected I want to avoid manually browsing for these systems. Is there a way to force specific systems to always be visible (but not all of them)? This way even if Dig thinks that the system has 0 roms, browsing it still triggers a rescan of the system.
