Good day! I own a MZ-NH900 and I wanted to know if it's possible to have a track under two groups (without actually transferring it twice), create multiple track programs, or play playlists of tracks, like m3u ones etc. I've searched the manual and I found nothing about it, but it surprises me that something so useful can't be done, so I've decided to ask here. Thank you very much for reading this! Any answer will be very helpful.
