Could we have a tag on the boards that explicitly says "A Rioter has read this, but not commented"?

By this I mean not the current Rioter Red Post system where you can see whether or a Rioter commented on a thread, that's fine, what I would like is one where you can see if a Rioter has read a thread, but not commented.

This would show that Rioters are reading and listening to the community, but cannot give any information regarding the topic because they may need to keep something confidential. I think that having such a mark would assure the community that their discussions are being read.
