Betty_fisher5 has a point, that's way too slow for production work.

Stick with that strict system, it's a lifesaver. My old shop used a similar code sheet where 'A' was for architectural, 'S' for structural, and so on. We'd add a detail like '-NEW' or '-DEMO' after the main name. So you'd have 'A-WALL-EXISTING' and 'A-WALL-NEW' right next to each other. Makes turning stuff on and off a breeze. The key is getting everyone on the same page so we're all using the same abbreviations.

Forest" with just gray is wild. That warm color check is a solid move.
