Control the scroll position of the Locals window

I'm working on an extension for VS 2012 and 2010. We have implemented a language service and a debug engine.
 Is it possible to control the scroll position of the Locals window programmatically (either directly or indirectly)? Maybe scroll to the top of the list? 
 The current behavior is: if you hit the same breakpoint repeatedly in a debug session, the window will maintain its scroll position. But in subsequent sessions, the scrollbar will move down until it is at the bottom of the window. This happens in C# as well as in our programming language (Intent).
