Compensation Hierarchy Determination Fast Formula to use as Reviewer for entire population

We'd like to use the Compensation Hierarchy Determination fast formula to use it in the Reviewer hierarchy so that these persons can see the entire population.

This scenario is given (more or less) in the documentation here: https://docs.oracle.com/en/cloud/saas/human-resources/22d/faiwc/workforce-compensation-plan-hierarchies.html#s20050733

"Country-specific HR specialists need access to everyone in their country, regardless of who people's primary plan managers are."

In our case, we want to give the persons in our setup with Grade 'Partner' or 'Managing Partner' the rights to view everyone. If that's not possible, we can base it on PersonID / AssignmentID.
