Sharing "Break Rooms" Between Departments

Is there a way to mark common/break rooms for staff of two or more departments as a "shared" break room? I have my radiology department right next to my emergency department and my staff from radiology don't use the emergency break room that is right next to them. Is there a way to share them or designate which ones each department can use? If not, can we implement this feature in the future.

When I only had one staff room, my staff from all departments were happy to share it. When I gave each department a break room, the staff insisted on using their own even though they were working in a clinic room downstairs and the rest of their department and break room were upstairs. I can totally see why they'd feel more comfortable with their own colleagues so I guess it's realistic. But it was kind of a waste of time
