Option for Attaching Different Keybinds to Different HUD Layouts

This is something I've thought about for a while, but it seems more important than ever with the introduction of the Perform system.

Basically, I'm already seeing some people wonder about keybind change macros or if you can attach a set of keybinds to another HUD Layout. I'm definitely one of those people. The keybinds that are comfortable for combat aren't necessarily comfortable for using Perform.

Being able to save different keybinds for each HUD Layout would pretty much solve the problem.
