Changing the RSS metadata of a show, to be different from that of its master feed

Can I, and if so, how would I go about changing the RSS metadata of a show, so that it can have a different category from its master feed?

To give an example, my podcast is listed under the Society & Culture category, but I created a show with all of our gaming-themed episodes, and am hoping to be able to take that feed and submit it to iTunes. I’ve already added everything I could via the shows section of the podlove panel, but there seems to be no way to change the category and the explicit rating.

While this doesn’t seem possible at the moment, are you planning to implement this in the future? I’d also like to be able to mark separate podcasts as complete.
