You've got 1 option for sure (and a second if you have Microsoft Access). The least complicated is to use the song edit screen to delete any and all songs that have that diskid. then reimport using the bookid you prefer. If you've already imported something that has taken that number you've got complications. You'll have to use the edit screen to delete thos as well and then reimport those after you've finished with the first ones.
If you've got Access theres a way to do it without deleting and reimporting anything. If you've got it post back and I'll go through the procedure for you.
