How to modify Axis Blitz scenerio?

[32shaw]

How can I modify the regions set up in the Axis Blitz scenerio? As that scenerio starts in 1939 I tried using "goldregions39.txt", but that didn't work. Using "goldunitdata39.txt" did allow me to modify the beginning attack, evasion, etc unit levels at the start of the Axis Blitz scenerio, so I'm a bit confused. Thanks. 32shaw
