SAP GRC 12 - EAM Access Request Workflow additional rule

I have configured SAP_GRAC_ACCESS_REQUEST workflow for EAM (Firefighter). Currently all approvals go to the Firefighter owners.

I now have a requirement that if the Firefighter belongs to the Finance Department there is a Manager approval before it goes to the Firefighter owner. How is this configured? Can I use standard configuration or do I need a BRF rule? Can someone please guide me.
