The files can be previewed and as you can see you'll be able to edit these maps to your liking. You'll need Photoshop CS6 to use, but I'm sure you can get it for free somewhere.
For those not really familiar with Photoshop, you have to open the photoshop file into the software and then once thats done, unlock it, and duplicate the layer you want to duplicate. Once duplicated you can move that object respectively. There's probably a much less crude way of going about this, but this works so yeah.
