I know this has been mentioned many times but , maybe a rolling barrage could be set up. Like now you can set pre start point, area, linear zones,with duration, saturation, and purpose. Seems like a rolloing barrage tile could be added under the arty selection ,point,area,linear,...rolling. You can Set these at the beginning , or even mid game , providing LOS after start. Just have the , rolling tile , allow multiple entries ,after you set the the tube, type,duration , general personnel, and the time. The time selection , immediate, five , ten , fifteen min , could be linked to a adjust fire command , and you set the next waypoints , up to four. just without the spotting and recieving time delay , there could be a briefer preparing delay , coordinate adjustment only. So with what is currently in the game, almost, you could at least set up four linear,area,or point rolling barrages. And this would most likely have to be set before turn one starts , as LOS , unless you have multiple drones, prevents you now from making just ,coordinate strikes , all over the map.
