Auto Blog - Expiring Posts function?

I'm using feed wordpress for a site, not 100% happy with it. Does Auto Blog have the capability to remove posts when they disappear from the feed? In my case I am taking a RSS feed that has jobs on it, and these jobs expire. The site owner wishes for these to be automatically removed from the site without him doing anything. Can this plugin do that?

If this cant be done., could it remove posts after a certain duration on the site? ie 2 weeks.

Thanks
