If you merge an object that’s linked to a parent object in a source scene, and an object of the same name as the original parent exists in the current scene, a dialog appears asking if you want to link the incoming object to the existing parent object.
Reparents the specified object and continues prompting for all subsequent merging objects that might need reparenting.
Reparents the specified object and all subsequent merging objects that need reparenting.
