A friend and I are working on a map. While he was fiddling around with the terrain on his own computer, I made a dummy map and made some custom items, units, abilities, triggers, etc. When he finished the terrain he e-mailed his version of the map back to me. I want to import the stuff I made on my dummy map into our real map. However, we already have some custom data in the real map.
How can I import the new custom stuff without deleting the old custom stuff?
