Sort of. There is no way to do it so that it will be easy to do when making the map in the editor. However, you can achieve the effect in game by a script that takes another map and uses it as a layer. AKA, you make your base map, and then you make another map that is the same size and it could take that map and draw it on top of the base map in game, thus making it look like you have a lot of layers. It is a little hard though, as you have to draw the layer map without easy reference to the base map. Anyway, I believe that such a script exists on RPG Revolution.
