Is there any way to store an empeg profile someway such that I could reorganize it, add mp3s and such, but only have to pull the player out of the car at the end to do the final sync? Maybe have the local JEmplode store diffs to the profile until I do a sync? My time to play with my music collection is pretty fragmented right now, so I'd like way to work on my playlists without having to have my player actually plugged in...
