I installed cheat engine speedhack (single player only !!).
It allows you to slow the game down and even lets you pause it while you can still give orders. http://www.cheatengine.org/aboutce.php
Cheat Engine is an open source tool designed to help you with modifying single player games running under window. It comes with a speedhack and more options (but these you don't need to to slow down games).

I suggest you only use the version without Open Candy (thist could be considered to be Malware)

Now run the game
Alt tab back to cheatengine
Select the game process in cheat engine by clicking on the computer icon (the icon will be blinking)
Check enable Speedhack (You can add ingame shortcuts in cheatengine through Edit-settings-shortcuts)
Alt Tab back to the game and play
I have used this for Wargame Airland Battle (and other RTS : Company of Heroes, Men of War series, ...) to introduce a kind of bullet time to this game.
