How to change Sombra's Passive cooldown through Workshop?

Hello, I’m trying to make CD Spam mode for my friends to have fun, but there’s one specific hero that I can’t fix, and it’s Sombra. The problem is that reducing overall cooldowns for everyone through Heroes → General tab, it reduces her passive cooldown too, and it messes all her stuff up. I haven’t found a way to bring it back to 2.5 seconds through workshop code, so that’s why I’m asking for help. Is there any way to do it or it’s just L for her?
