Hm, actually I always imported single files or batch import with CSV. So I never tried it any other way. But I always thought you could import a file with several bookmarked songs so that it automatically creates song entries similar to the CSV with a file with multiple songs.
This "batch import" option with bookmarks should seriously be added to MSP. As I said, I already thought it worked this way.
