this is more a QoL suggestion, plus it might help cut down on people using group chat.
well i used to play on another server a long time ago before i came to asylum, they had pub cop slots(which was aids), but the thing i liked was there were hot keys for back up requests or in pursuit. examples being
alt+numpad 5 = code 5 = requesting higher up
alt+numpad 4 = code 4 = all clear(meaning you are not in pursuit or in an active fire fight)
alt+numpad 3 = requesting backup(in active firefight)
alt+numpad 2 = cant remember exactly but i think it was suspect apprehended and is being processed
alt+numpad 1 = in pursuit of suspect
and when anyone changes there status a notification appears for all officers letting them know whats going on.on the map your name will also be altered so it adds code 1-5 at that end and it will change when ever status is changed so it will have to be changed back and forth when needed, i believe it was also color coded. dont remember what the color code was though, that way it stand out easier when someone needs backup
