Need help removing Autoblog's Duplicate Post Safegaurd

I need help removing the duplicate post or already processed post guard that restricts autoblog from allowing the feed to process the same post multiple times.

The feeds I'm dealing with are Open Houses and they change constantly. Plus, it's totally possible for an open house to be open for multiple weekends. Autoblog wouldn't process that feed, though, because it would see that the title (the property address in this case) was already in the processed log.

Also, my feed is arranged by price, so as more houses are added, the most expensive might still be at the top with new content below it. Autoblog, though, would dismiss the ENTIRE feed because of the first "post."

Help!
