Add Agent Field to Report in 3.1.2

[zerotoxic]

Hello,

On OTRS v3.0 you had the option to add the "Agent" field on a report of open tickets, I have recently removed v3.0 and installed v3.1.2 and cannot see the option to add the "agent" field to any of the reports. Has anyone come across this or know how to add it?

Thanks
Damian
