Macro Face Buttons

[FastBrad]

Hello Fellow modders.

I have many successful rapid fire mods, and my latest was the Flex mod with the addition of auxiliary A and B buttons under the pad.  My question today is, is there a way of having those buttons not directly soldered to specific buttons, but have them to a 2nd chip which you could assign any combination of two buttons under the pad. 

Here are some pics of my latest install to show you that I have a general interest in this, and that I am not one of these eBay scalpers





I also had one of the original spitfire mods aswell.
Cheers.
