fuze + external sd card + playlists = problem

Has anyone used the Sansa Fuze with an external SD card installed with Rhapsody playlists yet? The problem I see is: if i have a playlist on my fuze and I click the “auto transfer” checkbox for that playlist, and then I forget to uncheck it, the next time I plug in my fuze w/ Rhapsody running, it wants to duplicate the playlist on the external SD card. It starts downloading all the tracks in the playlist that are already in internal memory to the external card. I have to remember to uncheck the “auto transfer” checkbox each time before unplugging and closing Rhapsody. Has anyone else run into this issue? Does anyone know a way around it? I’d like to keep “auto transfer” checked if at all possible.
