Is it possible to allow each unit in your army to place fortifications down anywhere as many times as they want? For example, if before the battle started, I noticed that each infantry unit can only put down one and if you move them the breastworks went away.

What if I clicked the button and the thing stayed there and I can make as many as I want. Same with the stakes and cheavau de frise? Is it possible through any kind of modding?
