I'm also frustrated by having the button icons for my Thrustmaster TX wheel show as "3" and "5", instead of X-Box-style button icons like "X" and "A". In DR1 I was able to edit some xml files to change the icons to match how they're labeled on my wheel, and it makes all the non-driving parts of the game so much nicer to use. I was also able to fix the button icons in F1 2017 by editing some xml, so I had hoped that this would be a standard thing you can do for any Codemasters game. Unfortunately I never figured out how to customize the icons in either Dirt 4 or DR2. It would be great if the button icons displayed correctly out of the box, but I would be happy if at least I could customize the icons by editing the xml configuration file for my wheel.
