Rules for downloading new podcasts... or not!

Hey
Here's my idea. I would find it useful to be able to set a rule in order to get only some episodes from a podcast.
For instance, I suscribed to Au coeur de l'histoire and I'm only interested in episodes whose title start with "L'INTEGRALE" and not "LE RECIT".
Same thing with La revue de presque : I do not want episodes whose titles start with "TEASER".

Could this be done?

cheers
