I like my maps to be symmetrical, and I wanted to know since a casual poking around didn't find anything: Are there any commands or tools in the Starcraft 2 Galaxy editor to assist with making my maps symmetrical? Even an ability to export the heightmap for editing would work.

Highlight the terrain, copy and paste it, but don't place the copied terrain yet.
Under the Edit menu, use the Flip and Rotate options to get it symmetric.
