Select and move / copy / paste multiple object at once in the tree

[ShuffleWire]

Is your feature request related to a problem? Please describe.
When I want to move many object to a new place in the tree (for instance moving a bunch of building in a group), I have to do it manually by coping(or cutting)/pasting each object in the destination. (and no drag and drop)
Also, when I want to compare visually the position of two object relatively to each other in the scene, I have to go back and forth in order to display the origin (for instance checking position of two connector when debugging why they do not connect).

Describe the solution you'd like
The ability to :

• Select multiple node at once
• Display multiple origin and axis at once
• Be able to copy / paste them at once
• Be able to drag and drop node

Describe alternatives you've considered
I have to process each one individually.
