[Bigbox Controller Mapping with multiple controllers]

I'm using the controller mapping option to control navigation and various features of bigbox with a game controller.   My game controller usb encoder doesn't have enough buttons for all the mappings, so I want to use some of the buttons from player two controller.  When I map the buttons from controller two in BigBox is only sees the button as Button 10 regardless of controller.  It doesn't differentiate between the controllers.  I have controller 1 button 10 mapped to something else.  

Any thoughts on how to solve this problem?  Is there a solution?

This needs to get fixed or better yet.  I would be great if Launchbox had builtin control overlay features.
