Sub folder structure for playlists

[m00dymann]

I'm running Feishin with Jellyfin and I'm trying to figure out how to get Feishin to recognize my the sub-folders as playlists.

My music directory is sorted in genres like:
C:\Users\XXX\Music\Electronic
C:\Users\XXX\Music\Rock
C:\Users\XXX\Music\Jazz

Music being the assigned Jellyfin directory.

I would want the sub-folders to appear as separate playlists in Feishin, but only way to achieve this that I've found so far is to make individual M3U files for each folder and manually update each file when I bring in new music.
Is there any better way to optimize this?

Thx.
