@aaronsteers Something like https://github.com/edgarrmondragon/citric/blob/master/.sonarcloud.properties might be needed

Thanks, @edgarrmondragon . Very helpful! And to clarify, do you know if we need this once per project or if it can live in a org-wide repo used for sonarcloud settings?

@aaronsteers Unfortunately I think this has to be set per-project 😥

Thanks, @edgarrmondragon - A moderate headache for sure, but not impossible to manage. 👍
