Is there a way to allow a requester to view requests from all departments they manage?

We're a single organization using a single site. We have directors that manage multiple departments and want to allow them to view the requests from all the departments they manage. Currently, they can only see the requests for the department they belong to themselves.

Is there a way to make this happen without allowing the requester to see every request under the sun?
