There are different settings levels:
Global settings, or default settings, cannot be changed. Project settings can be - they are saved with your project.
You can clone Global settings and change those.
Go to Editor > Code Style > <Language>
Like any settings, you can configure project specific styles or global ones. What I did was to create an "Intelerad Coding Style" global style. I then copy it over to the specific project I'm working on.
