Changing Corridor Design Stage via keyin or vba?

Hi all,

Does anyone know of a way to change an OpenRoads Corridor via a keyin or vba? I've been trying a few methods and they don't seem to be working for me.

Using the macro recorder, when I change a corridors design stage to "7 - Final Linear Features", it gives me a keyin of "CIVILMSTN SETPROPERTY Corridor.CorridorDesignStage=7 - Final Linear Features,true ", but it doesn't seem to do anything when I try to use it.

If I try to change it in vba (using the Property Handler) any attempted change in value for "CorridorDesign Stage" results in "Not Available".

Any help would be much appreciated.

I'm using MX SS4 MR1 (Build 08.11.09.845)
