Working with local files?

[Vctrsnts]

Hello.
First of all, thank you for this application.
But I have a question about how it works. I see that there is no problem with the RSS feeds that we add and that you can add the RSS feeds you want.
But I have a question about whether you have podcast files that you download, if there is a way to add those files and that through the RSS that podgrab generates you can have access to them.
Is this functionality available? If so, what do you have to do to be able to use it.
Thanks
