Frequent/Regular non-seasonal downloader

[datdog]

Say there's a program that is not split into seasons/episodes, but rather is dated. I have an RSS feed for the program, but it has multiple entries, for example:

My.Program.2015-09-02.something.else.here.whatever
My.Program.2015-09-02.same.same.but.different
My.Program.2015-09-02.this.is.getting.repetitive
My.Program.2015-09-03.something.else.here.whatever

In the above examples, I only want to download *one* of any date that the program aired on.

Is there anything that does this already? Otherwise, I'm thinking of a Pre-Queue script and a Post-Queue script I could write to facilitate this...

A pre-queue script would be the only option for now.
Or a maybe a clever front-end to SABnzbd like SickBeard of CouchPotato.
