Rekordbox - Playlist formula

Hi there,

Not sure if this can be done in Rekordbox but I feel it would be an excellent feature.

If you could have a special playlist that can be created as to which specific parameters can be added in order to auto fill and update it. 

For example i would like that playlist to exist so I can call it "New Tracks" say and every time i add additions to my playlist it takes the latest 50 tracks of my collection and bam playlist made.

Look forward to hearing from you.
