VMWare Horizon View 6.1 and OU placement

In Horizon View 6.0 when you were setting up your Desktop Pool there was an option under guest customisation where you could specify the OU that you wanted the pool to join, which was really useful ! But in 6.1 this option has gone ?? Does anyone know how to tell your new VDi desktop to join a specific OU rather than Computer !!! in 6.1 ?

Thanks
