Meta Stack Exchange should have an option to feature a question which isn't visible to other SE communities.
For example, consider this question: Do we want accepted answers unpinned on Meta Stack Exchange?
This question should be featured because it is important and decides the future of Meta Stack Exchange. Other sites also have featured their "Do you want the accepted answer to be unpinned on this site" Meta question, and ideally we should too, since this is a very important question and can change the future of the site. However, the problem is that if we use the featured tag, it would appear in the community bulletin box across the Stack Exchange network - but this question is not useful/relevant to other communities, only for Meta Stack Exchange.
So I would like to propose a feature for moderators or staff members that would allow them to feature a question only in MSE, and not have it appear in the "community bulletin" box outside of MSE.
Maybe a way for moderators to set a Meta SE site banner or another way to advertise matters of importance.
