Hello pooky73,
Right now, the remap code and utility allow you to re-assign any of the 14 buttons to each other. You can make them all R1 if you want. What it does not do (right now) is assign 2 buttons pressed at the same time using only 1. But, I can look into updating the code and utility to do that. It will not be something that will be available overnight. The good thing is that any updates like this can be loaded into an already modded controller since the design uses a bootloader which allows code updates in the future.
As far as me personally doing this mod to your contorller, I dont have the time. But you can post a request in the 'modders for hire' section in this forum and get a bid from one of the guys to do the mod for you. These guys do mods all the time and are highly qualified. The files are all posted publically.
