I just purchased the second season of Melrose Place.  Whoever contributed to the database for this missed adding the 7th disc in the box set. 

I don't know how to add just that disc.  When I try to add it by disc ID it says that "Melrose Place: Second Season" already exists.

Is there a way to copy the profile for disc 8 (since they both use the same front and back cover art) and just change it to disc 7 and change the disc ID to the correct one?
