Temporarily Close after last reply

But can this be done automatically after each reply?

I like this feature for creating a slow-chat functionality. Also I have topics for customers where they can report service downage and there is no need to have more then 1 report each 30 minutes, for example. Manually moderating this all is a pain and rejecting posts is not the most friendly thing to do because people do it with good means. So closing after each reply for a short time would be perfect.
