How to add project settings tab

Hi, after reading this question (https://intellij-support.jetbrains.com/hc/en-us/community/posts/205973224-Project-and-Module-settings-and-settings-panel?input_string=How%20to%20add%20project%20settings%20tab) and the answer, I understand that it is not possible to modify the existing settings views in the "Project Structure" dialog. However, is it by any chance possible to add a new settings view similar to "Project", "Modules", "Libraries", etc?

I am writing a plugin that adds support for a specific language, and I need a place to add UI for project-specific configuration settings. This seems like the perfect place for this.

Thanks :)
