I think I might be explaining this wrong. When you look at the map of Durotar, you see the notation on the map for Ogremar, Razor Hill and so on. When you enter Ogremar, the map changes to a more detailed map with a close in view.
What I was hoping to do, is the same kind of thing, but with towns like Razor Hill. When you enter Razor Hill, the map changes to Razor Hill. Or when you enter Gadgetzan, the map changes to a detailed map of Gadgetzan.
Here is a sample photo I found of a few of the town maps:
If this cannot be done (which I have a feeling that it can't, since I believe that the capitol cities are considered their own zone), then I was thinking of a plugin (like Atlas, or the portion of Cartographer or Metamap) that displays the instance maps.
