So every time I start a new city, I delete all of the starting highways so I can build my own. The problem is that a lot of map makers like to put a lot of trees around their highways and when you delete them, there's a bare strip in the trees where they used to be. An Import/Export feature would be great for solving this so I dont have to manually select all the trees that the map uses to put them in a brush. Then map makers could include an import file for their maps and it would be less work for all of us.
