Cannot store audio and video in the same playlists

I am a Serato user who wanted to try rekordbox. I also have over 6000 music videos that i use in perfomances as well. In Rekordbox you cant seem to store audo and video in the same playlists. This is really troublesome since you now need to maintain 2 sets of playlist and search them separately. Also, the fact that I can't add tags to my videos makes it even worse.
