Problem you may be having, or feature you want:
The process for making podcasts from disorganised files hosted somewhere on the Internet is very fiddly. Either you need to create an RSS file by hand and host it yourself somewhere else, which is a step too complicated, or download all of the files and create a podcast from a folder, which takes up a lot of space and is less flexible.
Being able to add local RSS files as podcasts, not just virtual RSS feeds for local folders. The UI could just look like using file:// links in the link field. Preferably also support pulling media files from file:// links, which could allow this to be a more customisable alternative to local-folder podcasts, but I’m not sure that this is possible or reasonable (or that you can easily limit that to local RSS files).
