This could make sense, but may require the ignore feature not mute for what you are talking about to hide posts in a topic that aren’t specifically addressed to an individual who wants to mute/ignore a staff-member.
That may already be possible as is the mute feature for staff members but requires user be at trust tier #2 to be able to use the “ignore” feature. In the context of if a staff member is making posts on a topic that are not important staff announcements, then those could be minimized out if folks are wanting to focus on talking to other people.
