[otrs] Reg: Adding new link in Customer screen to approve tickets.

Hi All, Just like CompanyTickets in the Customer Screen, I want to develop a new screen called Approval tickets that would list all the tickets that would require an authorized approval. This links should list all the tickets that are to be approved by an authorized person(Manager). So Just like follow-up. When the manager clicks the link on the ticket, it should allow him to approve/reject a ticket. If someone has done this, please let me know how to achieve this? Any help is greatly appreciated. Thanks, Lokesh
