Protect a custom RSS feed with this plugin?

I have a podcast website with a LOT of episodes. So many that the RSS feed can’t show them all. I want to create a new benefit for my patrons for a ‘classics’ RSS feed that shows the oldest episodes so patrons can plug that feed into a podcast app and download all of the old episodes easily.

I don’t know how to create that kind of feed but I assume it can be done. My question is can this plugin protect a certain RSS feed so that only patrons can access it?
