For box sets and 2 CD sets, etc. Simply get all of the discs separately from the CDDB. Rename disc 1 to the proper title of the set (i.e. Dark Genesis (Box Set)) and fill out any information you want, then save it. Then go to disc 2, and rename it to name::2 (i.e. Dark Genesis (Box Set)::2). Make sure the spelling is the same, the only difference should be the ::2 at the end (no spaces before or after it). It should then combine those albums into a 2 disc album. For disc 3, just do ::3, etc.
