title: Nested navigators with intermediate views
body: <p>I am using react-navigation with react-native to create my app.</p>
  
  <p>For a variety of reasons, I need to create nested navigators where the inner navigator is ensconced in a view. So my structure looks like:</p>
  
  <p><code>Drawer
    Screen1
      View
        View
          SwitchNavigator1
            ScreenA
            ScreenB
    Screen2
      View
        View
          SwitchNavigator2
            ScreenC
            ScreenD
  </code>
  Setting things this way creates a bunch of inconsistencies in routing. My guess is that the SwitchNavigators are not "connected" to Drawer (i.e. Drawer is unaware of nested child navs). Is there a way to establish parent-child relationship between nested navigators even if the descendent nav is not a direct child of the navigator?</p>
