Feature Request

I confirm:

• That I haven't found another request for this feature.
• That I have checked whether there are updates for my system available that
  contain this feature already.
• That this would be a sick feature to have.

What I'm requesting:

-I would like for proton to update the directx .dll files in /home/deck/.steam/steam/steamapps/compdata/gameid/pfx/drive_c/windows/system32 (and /windows/syswow64) for proton experimental. More info below in the "In Depth Notes"

Why Proton and not Wine:

-It would be more convenient for steam deck users (and everyone) to add this to proton instead of wine.

Possible Issues:

-I don't know why this hasn't already been done, maybe because updating the .dll files might mess up other games. This is why I suggest this feature being part of proton experimental.

In Depth Notes:

-The .dll files that bottles use would be perfect for proton experimental. When testing the knuckle sandwich demo on steam (through any proton version), it crashes at a certain point, giving a directx error. When running through bottles, it can be run
all the way through with no issues. I decided to run a test: I transferred the /windows/system32 (and syswow64) files from the bottles directory to the steam compdata directory /windows/system32 (and syswow64) files and ran the game as normal, through the latest proton version (the one I has used before). The only difference from before was the transfer of system32 and syswow64 files. The game ran perfectly fine this time, and I hope you can integrate this feature as a default for users who do not wish to tinker with the game.
