Remapping L1 and R1

[Keg]

I haven't tried remapping, but you can draw/sheathe your weapon by pressing L1 + R1.

Thanks, I wasn't aware that L1 + R1 drew your weapon. Ideally though I'd like to remap L1 to Lock On. I've been skimming through menus for the past hour trying to figure out if it's even possible.
