Delete entrenchments from scenario

[Weasel]

The map I created is facing in the wrong direction for retreating unit purposes. The Chinese are attacking from the north to the south, but when they retreat they are running across the front of the Marine positions to the right; resulting in squads being wiped out post haste.

I changed the rally hexes but that only affects their end of turn routing route, during the game they are ignoring the rally hex. Therefore the only other option is to spin the map 90 degrees so north now faces to the left (west) and south faces to the east (right). I tried using the editor copy map and past function but there is no way to spin the map that I know of.

Is there a way to spin the map? If not, is there a way to stop the Chinese from running across, or through, the Marine lines when they are routed? They need to run north and the Marines south (although Marines don't run).
