I am using multiverse on my server, i use it to have multiple layers on my two maps, how do i have dynmap render the top layers over the lower?

I need to figure out how to render maps on top of each other. is this even possible? I have 7 maps that render on top of each other. one lower, The main one, then 5 others that only have a few blocks in them. like a top of a mountain.
