Mines in Game

[Vorsteher]

for my Kursk scenario i want make mines.
Okay, i set a new landscape type with movecost for all movetyps : 80 APs.
Mines only can set to normal plains.No mountains etc.
Now i set a new loctype as minefield. Engineers can now blow the location and set the landscape back to plains.Until here all okay.
Now my problem, when i set a minefield on a plain with a road,no effect more with the minefield.Roads have own rules to the consumption of the actionspoints.
How can one solve that?

Could you remove the road in the same action as building the minefield?
