DK Death Gun

I'm playing pz on splitscreen mode because my gf doesn't have a pc. so, i'm always trying create new ways to improve the experience, one of these was use two monitors to show each player screen. But, a trouble i found was that the sound of each player plays together,. i'm searching a way to set each player ambient sound play from different speakers. I'v asked into pz discord bt there isnt anyway right now to make this work. So, i'm suggesting to add this in the game
