Limitations in Location Tree Modification

[pLeminoq]

Currently, the only way to change the location hierarchy is by modifying the placement of a location.
Why isn't it possible to modify the hierarchy by setting the location child ids in the location config of the parent location?
This would speed up registry modification (especially for an initial setup), since setting the placement for all children causes more modifications than setting all children in the parent.
Verify if it is possible to handle both modification types by considering which location caused the registry modification.
