Purchase Order Release and Save on Release Button click in ME29N

Dear Developers,

My company MD has asked for single click release and save option in ME29N Release Button. This option will be for him only and rest all users will be Releasing and then saving. We are using S4HANA 1709 version.

Please help suggest with any BADI/Exit/Event Trigger etc or if any direct changes required in SAP module itself..

Regards
