A way of "removing" an cargo acceptance at a station

If I allow a train with a passenger wagon to accidentally pull into a station that ISN'T designed to transport passengers, it will automatically add passengers to that station's cargo list and passengers will start to arrive at it. Because no other passenger-carrying vehicles will ever reach that station, they sit around for ever. If you keep an eye on the station list window in order to find any stations that are becoming crowded, it's very distracting to have two thousand passengers sitting on a station that will NEVER transport them.

What I would like to see is a small cross by each cargo type under the station "ratings" lists. Clicking that cross will remove that cargo type from that station forever (or at least until another train with a passenger wagon comes along to that station) and hence stop passengers accumulated at that station.
