I looking for Information on how to change the cockpit dash board of the MSFS24 Piper Arrow III.

What I would like its to just have a section of the cockpit just a purple chroma colour and use it as pass through.

The image above shows what i can do with SimVr app to draw boxes to display but actually using the colour ingame would give a crisp cut out.

I have a little experience with painting the exterior so maybe just what files and where they are located would be a start.
