Rekordbox - Waveform colouring as a song tag/label

Similarly to How scenes work - we could be able to assign a base colour of a waveform to a song parts.

This would allow us DJs to have another visual clue to what can be expected in the song. For example I could label song parts that contain vocals with red to know right away not to mix in the other songs vocal part too in advance. Or I could use it for labeling an intro / outro etc.
