Touch OSC syntax

Hey chaps, I like the touch osc control its really useful on set but what would be wicked would be if I could build up a page with all my groups on it and a keypad so that I can control the levels, does anyone know if this is possible?

I've created a layout with the keys but I can't figure out if its possible to assign them to specific groups or if I can run a macro say hog/hardware/group 8 enter...

Thanks

Tim
