Hello Brian, thank you for raising this topic.
Your request looks similar to this one. The answer remains that, currently, the only available option for having project-level rules configuration is by using SonarLint in Connected Mode with SonarQube or SonarCloud projects. This will ensure that the same rules are applied locally as on the server, hiding the Won't Fix and False Positive issues configured on the SonarQube or SonarCloud side.
The feature suggestion to be able to Import/Export local ruleset from SonarLint exists on our Product Roadmap page. Make sure to vote for it if it is important for you 
I hope that helps. 
Best,
Sophio from SonarLint :sonarlint:
