Allow Requesters to have secondary email address
I constantly find new requester names being created for users that already have requester IDs in the ServiceDesk. Sometimes, it's because they use a different email address than the one in their requester ID. It'd be great if you can add secondary email addresses to the requester ID, and then also have ServiceDesk know to link the corresponding requester ID to the user when they email a service request with their secondary email address.
