Question - is there a way to "auto" download prior podcast episodes without manually selecting them via the guides and downloading one-at-a-time.

I've scheduled a podcast to start downloading today and forward, but not sure if there is a way to download past episodes of the same podcast automatically. I know that I can select a prior episode one-at-a-time and download that and it is very easy, but in my case, I have over 100 episodes I'm trying to go back and download.

Thanks for any help!
