Why is there no x, y, and z coordinate for box? As well as possibly other 3D Shapes?

I am happy with the new additions of 3D shapes, however there is no setting there positions.  I know there was an issue of where do we start x,y,z is it at top left, or middle.  It seems that using relocate(x,y) works for now, but there is no z, so I would have to do z translations.  I think location setting is important for all shapes we will use.
