Any way to assign a category to CustomPress page types by default?

I'm setting up a podcast hosting/community site, and I think this would help my users. I set up a custom post type called Podcasts, and the posts of this type are called Episodes. I have Powerpress installed so people can embed their mp3's in the post, but in order to get the feed to submit to itunes, the posts need to have the category "podcast".

Can I tell CustomPress to assign this category by default to the custom post type?
