Just wondering if anyone knows a way in the scenario editor to limit the max amount of resupply a unit can receive. In particular I'm imagining a stalingrad scenario/campaign where resupply for the axis would obviously be limited. I know it's possible to edit starting fuel and ammo for each unit but once the game begins the player resupply tell unit to full, defeating the purpose of simulating limited supplies.

Any advice/ideas are much appreciated!
