maintain Sorting within different playlists rekord box 6.85

Hi..

How do I maintain the sort selection within different playlists? I'd like some playlists sorted by the date added and some sorted by the order I added them. The sort selection doesn't seem to maintain what I leave it at when I exist a playlist and then re-enter it-it assumes the sort of the last playist I was working in ....

I hope that makes sense! I'd like my playlist to be independently sorted from eat other
