Itunes Multidisc album paired to phone

My issue is slightly different from the others listed. I have several multi disc albums when end up named:

Name: DISK1... When I sync my phone with the computer only 1 of the DISKs is copied. I have made sure the disks are separately marked to be copied and so forth.

As an aside it would be really nice if Apple provided drag and drop to allow manual copying of something from Itunes to your device etc. Would be a great workaround.

So the question is how to get the remaining disks within the album copied?
