Filter to De-Duplicate Episodes

I would like to have an option in the “Filter” menu to filter duplicate episodes, where you can choose to ignore episodes with (a selection of these parameters) like the same Name, Filesize, Date, Duration, maybe File Hash and many others.

Background: I have a podcast that seems to upload the same podcast twice a day, with 2 hours in between the uploads. I would be nice to filter for the same name in this case so the episode is only displayed and downloaded once.

The Podcast: https://podcastaddict.com/podcast/klartext-nyheter-pa-ett-enklare-satt/2138136

Some other podcast have duplicate podcasts once in a while, probably by accident or because they made a mistake in the first take so it would be nice to always filter for the FileHash, so if the audiofile is the same, there is no need to download it again, but if the audiofile is different it probably makes sense to get it again.

Regards

Markus
