I’ve had a quick search but can’t see if this has been suggested.
I like to try and keep the units from the correct authority attending to calls within the authority boundaries. To do that I have AAR’s set up so I can send them as such.
It would be good if we could ‘colour’ in areas of the map so that if I call is generated within a certain colour, only units from stations tagged with that colour can dispatch rather than having to change between different AAR options.
Having the option to allow a station to dispatch to multiple areas would be needed though as my ambulance trust for example covers multiple areas.
