Adding local files to podcasts

Is it possible to add local files to the podcasts library?

I’m hoping to add some folders of early 2000s podcasts to my Plex Server and would rather not store them as music. I imagine I could use some hacks like writing my own RSS that points to the files, but that feels like a way overbaked solution.

Is there a way to discover local files and have them show in the podcasts library? Or is that 100% online sources only?

There is no local file support in the podcasts section.
You can only add them as music, fully tagged in an Artist / Album / Tracks folder hierarchy.

Super disappointing. Thanks Otto.
