It's a small pet peeve of mine, but I'm working on a map and my northeast beyond the border custom house should be Soviet, while my southwest one should be Western.

While in landscape editor you have the ability to swap borders across the map, and new custom houses and connections placed down will economically align to whatever border they're placed on, but I see no workaround to get the beyond the border custom houses to switch sides.

I've even tried demolishing them in the landscape editor, saving after demolition, and reloading. They come back, but they always align to Dollars in the northeast and Rubles in the southwest.

Perhaps there's a line somewhere in the code generated in the save that would allow you to manually swap them, but I'm not too sure where to look as I only have a real basic knowledge of the game code for the individual buildings/vehicles and their textures.
