Add-in: How to get the user-selected breakpoint

Hi - 

Working on a C# add-in for VS 2013 and VS 2015 that provides a few UI elements for debug sessions.  

One of the elements is an enhancement for data breakpoints.  We can detect when someone wants to add a data breakpoint, and we provide our enhanced dialog for that, and it works as expected.

The problem we're having is when someone wants to edit that data breakpoint.  We detect the event, but can't figure out how to get the breakpoint they are trying to edit.  

Notice that we're not wanting to detect when a breakpoint is being hit by the debugger.  Rather, we need the breakpoint selected by the user in the Visual Studio UI.   (Even just the text will do.)  

Thanks!
