Include Podcast Media in Autoblog feed generate posts

We have a podcast feed we are brining into the blog. We can successfully get the podcast's to become posts on our site, but the audio content is not included or linked to.

We'd like to have the audio file imported to our media library when the post is created. At the very least, a link to the file would be nice.


Sample feed:
