So what i mean by this, have an option to call volunteers to the station that would respond to the station in their POV's. Whether its a Paid department they would be called to staff the trucks, and if the station is Volly select that option for the volunteers to be toned out or dispatched out to the station.
But i really do think it would be a good thing to have for people, to add to the realism just a tad bit.
