In this use case, tickets are received from the customer (requester).
An agent will pick up the ticket and become the assignee.
He will then use a macro to assign the ticket (and add info in an internal comment) to the Logistics group.
An agent from the Logistics group will then add an internal comment and then we'd like to create a trigger or macro to assign the ticket back to the original assignee, being the first responding agent in this scenario.
In this case Logistics group would not have to check who the original assignee was when assigning it back.
