Automatically delete feed items

Hi

We are using your software to display job vacancies from our HR system.

The feeds are displayiging fine.

Is there any way to delete feed items automatically when they are no longer in the feed?

The option is delete after a period of time is not suitable.

I just need to display the job vacancy feed items if they are in the RSS feed, and delete/hide them if they are not in the RSS feed.

Is this possible?

Thanks

John
