Differently sized battle maps

Much as how you changed the world map to have irregular shaped areas, it would be nice if we could also edit battle maps to better suit the area depicted on the image. Square or rectangular battle maps are limiting when it comes to circular areas like tower interiors. It is also limiting in irregularly shaped maps like caverns. For example, take the battle map below, I would want to edit the “walkable” are of the map so a character does not seem to be standing on the wall or in the middle of the door.
