I read about somthing like this in a supcom articul. They guy was taking critism at supcom and suggested if ther coudnt be like pre set patrole routes that could be numbered and randomly be filled with eny unit you want to fill it with.
So basicully i asking for a feature that gives a bottom in the left panel to set a patrole or three or more bottoms to set more patrolles end ones the patroles are set. By clicking on a unit and apply the botton again the unit will follow that patrole. This way old patrole routes could used more times.
