How to group all downloaded podcasts automatically?

I was wondering where, in the Podcasts iPhone app, I can find my downloaded podcasts automatically grouped together into one list, the way my iTunes Music and App purchases are.

I download only certain episodes of a podcast and listen to the others as streaming. It would be much easier for me to manage downloaded episodes if they were grouped together (regardless of whether they're different podcasts), otherwise I may lose track of them if I have to find them within each podcast. Is this currently possible? How?

The only work-around I've found is to create an on-the-go playlist containing all my downloads. But since I have to do this manually, it's annoying.

Thanks!
