[REQ] Sync folder to cache

[rubbersoul]

I was wondering if it would be possible to set up a folder(s) from the subsonic library to be synced to the device. I have a pretty big favorites folder that I'd like to stay synced to my device. I know I could star all of them, but I'm not sure how to do that without manually going through each artist ~300 and starring the album tree below. I'd also like to use the star function primarily to denote tracks I like for playlist reasons.
