Is there a way in calibre to search by device?
For instance, something like
- ondevice:devincename to search for books that are on a specific device; false if that device is not currently connected, as ondevice by itself currently does
- isconnected:devicename that is true if a specific device is connected, so I can have a branch of a saved search specific to a device
- isconnected:any for a branch of a saved search for any connected device
