convert audiobook to song

iTunes says that a certain file (in ~/Music/iTunes/iTunes Music/Audiobooks) is an Audiobook. But I want to put it into an Album, In fact it\s a talk, and many talks were given at the same meeting. I want to put all these talks into the same Album.

I don't really like being forced to classify a talk as a "song". I would prefer to have a new category like "talk", but that doesn't appear to be possible. Anyway, I'm only very slightly bothered by this. But I am VERY bothered by not knowing how to put this particular file into the same place/Album/folder/or whatever as the other talks that were given in the same meeting.

I looked this up in Google. All the articles are about converting songs into audiobooks. How frustrating!
