Allow to manually link (mixable, related) tracks with another

Everyone has this moment where you find a track which pairs really well with another one. There’s a whole feature dedicated to find “mixable tracks” based on metadata (which is barely helping for me) but no possibility to just store this information based on my own experience in a structured way.

Rekordbox has this feature to link (“associate”) two tracks with each other that are loaded into the players. But unfortunately, the display of this information in the side panel is mixed up and not to distinguish with other random stuff the RB algo considers suitable.

Please add the feature to have relations (I chose this term because there could be more types than “mixable” at some point) between tracks and if possible, allow to sync it with RB in both directions.

I can also see how quick access to this feature via the mobile app would be useful to log discoveries while mixing with hardware or while listening to a set.

This is an idea that is on the list but it’s not high priority currently, might happen some day
