Switching podcast RSS feed

I recently got my podcast approved and put onto the iTunes store. It's currently being hosted on Podomatic, but I've uploaded the exact same content to Soundcloud and been approved for an RSS feed there. My Podomatic RSS feed is currently what's being used on iTunes, but is there any way I can switch over to my Soundcloud RSS feed without resubmitting and recreating the podcast all over again? It seems that Soundcloud would be a better hosting site because it's free, the interface is aesthetically better, and I think it has more storage, whereas with Podomatic I believe I only get 500 mb of storage total, which means I'd have to archive old episodes elsewhere once I get beyond that limit. This is what I get for being impatient I guess. Please let me know if you have any guidance!
