How do I route ONR resubmissions to particular Program Officers?

I need to route an ONR resubmission to a particular Program Officer, what fields do I use for this?

SF424 field 4a (Federal Identifier)- copy the original Grant Tracking number from the Electronic Submission page, e.g. GRANT106012345

SF424 field 4b (Agency Routing Information) - Provide the Program Office Code followed by the Officer name in brackets, last name first, e.g: 322 [Einstein, A] Block 8 (Type of Application) - Ensure that the 'Resubmission' check box is checked.
