Is there a way to add a second layer on top of the layer switcher?

hello,

I'm new to Drupal, I'm currently learning and try to do development at the same time for a test site. I love the mapping kit module but i have question about it. Is there are way to add more layers on top of the layer switcher? Similar to firebox where you can open multiple browser and have a tab for each browser and you can go back and forth between each browser by clicking on the tab. I was wondering can you do the same thing for the layerswitcher where the first layer show the map base layer and it's feeds. The second layer might be a custom made layer for the legend, and the third layer might be for something else. And you can switch between each layers by clicking on the tab.
