Not that I'm aware of, but you might want to go ask over in the Kobo forum.
My method when adding a new book is:
1. Connect the book with the cable. Autoconnect will connect.
2. After the file sends to device, eject the device.
3. Open the SleepCover (if it already isn't) and wait for the 'importing' dialog to finish. (It sometimes takes a few seconds to detect.)
4. Use the 'USB Connect' on the menu to connect a second time.
Then I use a custom
Action Chain that uploads cover to device and pre-sets the font.
