Configure queries resolvers based on employees branch

Summary:

We have special setup in the system where we want to minimise data visible to many users;

We have employees whose first line of support should be Scheduler (our own role) but not any Scheduler but Scheduler in the same branch as the employee asking the questions.

Is there a chance to configure queries that they land in Schedulers in that branch instead of all possible Schedulers?
