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.
