Yes.

It sounds as if you have never used a version of the Book Sync plugin that has been upgraded for multi-device support. Once you have plugged in a device and used the Customize option for that device then you can add items to that devices sync list regardless of whether it is plugged in.

One big advantage of the updated plugin is that can now maintain separate lists for each device you own, and also separate lists for each card on a device.

KiwiDude: I wonder an "Add to All Sync Lists" option on the Books Sync menu might be a good idea once multiple devices have been configured? At the moment if you want a book on multiple lists you have to do each one separately.
