Can primitive object receive ref from mesh using instance?

[leminhtuanlc92]

Here is the idea:
I'm creating a tool that create a lot of object, obviously using instancedmesh is inevitable. Now I want to turn that whole chunk of instancedmesh into one new Object. Any idea to make it work, because I tried with ref (pass current ref of instancemesh nesting inside a mesh of Canvas A to a new primitive inside Canvas B) but it didnt show anything in canvas.
