Ability to access map layers in app

I have created a layer in the web version of spidertracks with kmz's from google earth outlining properties so that we can see what property our helicopters are operating on. This seems like its going to work perfectly with the web version but I am unable to utilize it on the app version becuase the "layers" tab doesnt appear on the app. The app runs a little smoother than the web version on my iPad so having this integrated as an option would be extremely helpful.
