Some podcasts I'm listening to on a weekly basis, and I'm all caught up. For those I want to sort by "publication date (new->old)". That way newest rise to the top and playback sequence goes backwards in time.

Other podcasts I may be just starting, with years of serial progression or story telling to catch up on. For those I want to sort by "publication date (old->new). That way the first episodes rise to the top and playback sequence progresses as intended.

As it is right now, changing the sort option affects all shows at the same time. I'd love if I could set one the one way and others another.
