Approval Workflow using Management Hierarchy + Manager's Grade

Summary:

Hi,

So the client wants to have this approval workflow and I was wondering if this is possible:
The baseline would be Management Hierarchy but if the manager in the first line of hierarchy doesn't meet a certain grade then the system will skip them until it finds the manager with the required grade.

For example, an employee submits a request that only managers with grade of 5 can approve. The employee's immediate manager (manager A) is only on grade 3 so the system skips them, that manager's manager (manager B) is on grade 4 so it skips them too, but this manager's manager (manager C) is on grade 5 so the system will have them take action on the request.
