Restricting roles by more than one department

Hi

I have a scenario where the departments are structured as follows

There is a manager (Joe Smith) who is responsible for all the departments that have a pink check mark next to them.

I want to create a role for them that restricts their ability to view or create transactions or entities by the departments they are responsible for.

Their employee record only allows for one department so I can't restrict by this.

Is there a way to restrict their role to departments in a structure like the above?

Thanks
