My recommended workaround for this would be to use a MyTag or even just add a number / word to the Label field so they match with that.
Include folders in the Related tracks criteria
It is possible to group tracks of the same, bpm, key, (...), and genre,
but it would be useful to cross-reference tracks from the same folder. For example The Dance folder may have multiple genres playlists, but they are from the same "musical environment".
Even better: the possibility to choose which folders to search from. eg. Within 1 folder or cross-reference multiple folders
Yes it can do. Thanks Pulse
