Macros in filenames for saving attributes

I make a lot of variations of the same basic map. It would be nice if I could call it "50x50 - %Terrain %Elevation %Water %Vegetation %Light" when I save it (or export it) and have DA automatically save that as "50x50 - Grasslands Flooded Ravine Island Steppe Dusk.DAM" (for instance). Feel free to make up your own macros.

This would save me from having to type in all those variations when I make terrain mods to existing maps, and make sure I don't overwrite one with the updated biome information when I don't want to. Feel free to apply this to exporting, as well.
