Create Custom Podcast RSS Feed Today.

I need these ([login to view URL]) events/shows to spit out in a podcast ready rss feed. We use modern tribe event plugin for the shows. We also have a second plugin you can use to create a custom feed. What needs to be in the feed is: -the audio -the short description -the guest fields -the guest resources/links fields All in the description portion of the feed. I am importing it into a podcast feed in goodbarber, but the current rss feed only displays the small description and not the guests or their resources.
