I know I can fire individual weapons in individual groups in succession with a single trigger, but is there any way to fire whole groups in succession with an individual trigger (using whats in the game engine)?

Chain firing groups?

Bind a key to fir the groups and use another to cycle through it. I used to do it was the CLRM10 Masakari. That mech was HATED at one point

Yeah, I want to use the joystick trigger only and I was hoping there was a way I could automatically set the mode to cycle between groups by flipping a switch, then it would switch groups every time I fired with the trigger. Kind of like hitting the "Change Firing Mode" control, but it only has two firing modes. It either cycles between weapons or fires the currently selected group. I think I can do this with a macro in my stick. Its just a little extra hassle I was hoping to avoid.
