2 player Screen flipping (cocktail machine) - MAME

This would be a great enhancement. At the moment it is necessary to set cocktail mode in the games’ a .Cfg file but this invalidates high scores uploaded to Launchbox’s Leader Board. I also use a vertical bezel that uses a marquee to fill the top of the screen which of course doesn’t get flipped through Mame. I’m looking for the game + bezel to be flipped 180 degrees through LB.
