Group By Option in Ticket List

We have many IT agents with managers that assign those tickets. Managers currently do not have a quick way to group tickets by assigned agent. There’s also no way to sort by assigned agent. We used to have this in Zendesk before moving to Freshservice. Please add this ability to Freshservice. We have managers complaining about Freshservice and they are generally unhappy because of a simple feature like being able to group tickets by assigned agent.
