Layering Dynamic Lighting in a stacked map.

I am currently building an encounter where I will have a map of a tower. I was hoping to have all of the levels of the tower stacked, so that when the players go up a floor, I can just send the current level to the back of the stack.  Is there a way to have the different dynamic lighting walls for each floor enable and disable with the current level? For example, attaching the dynamic lighting lines directly to each map image, so they only show up with the top layer of the map. 

There are some scripts that are capable of managing this.  I usually instead stack the levels in some way that makes sense and just move the characters between the areas.  This facilitates having the party split over more than one level easily: I'll often use one of the teleport scripts to let players move between the areas automatically.
