Rekordbox Intelligent Playlist new parameter (No-Tag)

As someone who uses the My Tag feature to fill intelligent playlists and narrow down tracks into different vibes and sub genres, I find it difficult to keep track of all tracks that don't contain a My Tag. 

I have too many My Tag's to create an intelligent playlist displaying all tracks not tagged.

Having an intelligent playlist parameter which displayed all tracks not containing any My Tag's, or not containing any tags from a My Tag section would help hugely in keeping the library organised.

Hoping it's an easy addition to the software and to see it in an update soon.
