Moving elements in a slide (design Review)

In Catia V5 we were used to overloading position in Scene.
In Catia V6 Scene are replaced by Slides in design review App.

I can not overload the position with Robot of a subassembly. For example if in a slide i want to change position of 3dpart_5:

-PhysicalProduct_1
---3dpart_1
---3dpart_2
---PhysicalProduct_2
------3dpart_5
------3dpart_6

I can only move PhysicalProduct_2
Do you know how to do it? THanks

Do i have to add a markup in PhysicalProduct_2 ?
