desktop cube

In past versions of KDE it was possilbe to have different wallpapers on all sides of the cube by checking “different tools on different disktop box”. Is this still possible? If so ,how? thanks

Basically in Plasma 4.x it was a hack for activities to allow this function.
As Plasma 5.2 is based on new code and activities work differently this feature is not yet available.

Thanks for your time.
