[otrs] Display order for Owner Agents in ticket creation screen...?

Hi again. It looks like the Owner field is always populated thusly : UserLastname UserFirstName (UserLogin) Is there a .dtl file og something where I can change this to: UserFirstname UserLastname (UserLogin)? I have already done so with AgentDashboardUserOnline.dtl, but cannot locate this other location.... Regards, /Martin.
