mute group in OS2

Might be in front of my face, but does anyone know where or if there is the group mute functions with the new os2, for when you wanna keep your program poly but have certain pads mute each other? I know there's other ways around it but this function i find makes it easier for closing open high hats and cymbals with other drums and avoids dodgy mute records and stuff. Anyone?

i dont think the gpe is quite finished yet, that could be a part thats yet to be finished

It's in Global Program Edit. The F5 button is shared with LFO. Press F5 to switch back and forth between LFO and MUTE.

cheers rad. doesn't display the mute screen when you scroll across using the cursors, thats where i went wrong. Didn't even see the mute there. Thanks

oh yeah thats a novel way of using function buttons, and i forgot about that.
