Option to add SQL based FYI BPM stage rule for ReqApproval

Summary:

With RSSP we dont have option to add approvers at the stage level, I am looking to add a new stage to include project approvers in the requisition BPM rule to receive FYI notification. Is it possible to provide SQL based FYI notification rule?

When I add I get attached null values. Please advise.
