Ability to view and message only expired sites

Is there a current way or planned way to filter the pro sites list and see only expired sites, then the ability to send an email to those expired sites with a message to prompt them to renew with a coupon code etc.?

Also the possibility of automatically trashing sites that have been expired for X number of days months etc. Our list is growing of sites that have not renewed and it is VERY difficult to find out which ones are expired without clicking on each one...out of 300+ sites only 165 are active.

So we are trying to market to them to upgrade or renew. If not we will delete their site.

Thoughts?
