Ok, I guess this was staring me in the face and I did not see it. 
I’ve found that if I want to duplicate a map, simply duplicate it. And if it has levels, go to the shared asset folder for that map and duplicate the levelinfo files, create a new equivalent folder “New Map Name- SharedAssets” folder, and move them over. Now when you launch the new map, when you look at the landscape levels, there is a place by each level where you can select which leveling files, you want the new map to reference. These will be the ones you moved over.
