title: Show overridden methods on Visual Studio Code Map
body: <p>I've got a hierarchy of MVC controllers inheriting from each other which I've visualised on a Visual Studio Code Map. What I would really like to see is where methods are overridden, so I can see if a particular method on a base controller is overridden on lots of derived controllers (to help me see areas for refactoring).</p>
  
  <p>I've been able to select a single method in a derived controller and see which methods it overrides, but I want to work the other way round and see what overrides a base method.</p>
  
  <p>Is it possible to see all methods which override a specific method on a base controller?</p>
