Well, you can hit auto deploy, but have the monitor covered except for the exit button (with a sheet of paper), so you don't see the deploy.

As i said, it works quite well if the computer is moving - because the AI is quite good in arranging its units for an assault - at least if it is army with poor tactics (like Iraq or or soviets in early WWII). I definately prefer to have a person set the AI up in defense or delay situations.
