Yes, you can merge. Select all the records, then right click | Edit Metadata | Merge-delete others.
If you turn on the autosorting option |Prefs|Add/Save|"If books with similar author and title found..." it will put the formats into a single record, or you can use the correct Add Book option to do this if you are entering them at the same time.
