Proofing Workflow - Comments on Private Stage

We have our proofing workflows set up with two stages: Internal (Private) and Client (Not Private). We have automation setup so that once the internal stage has been marked approved, the proof automatically sends to the client. The problem we are having is that sometimes there are comments made in the internal stage that the client needs to see, and there are comments we don't want the client to see. We tried @15076311 someone in the internal stage comments that is part of the client stage hoping that would give them a notification that there is a comment for them to review, but because the internal stage is private and they are not apart of that stage, they don't receive a notification.

So, my questions is, is there a setting where you can have it so that comments in a private stage can be viewed in a public stage if a member of the public stage is @16034 in the private stage? Or, if not, does anyone have a workaround they have implemented for something like this?
