[Booker T Nook]

I can manually remove books from my kindle device. But is there a way that i can have it to remove older news feeds that are like a few days old automatically when it is plugged in?

I get a bunch of old feeds piling up from weeks back. It would be awesome to have the feature to auto delete selected feeds after so many days without the aggravation of manually removing all the old ones.

Or maybe it is already a feature. I just dont know how to do this?
