reconnect programmatically instantiated prefab

When doing t$$anonymous$$s:

Code:

Object prefab = AssetDatabase.LoadAssetAtPath(newPrefabPath, typeof(GameObject)); 
GameObject clone = GameObject.Instantiate(prefab) as GameObject; 

I can't do:

Code:

EditorUtility.ReconnectToLastPrefab(clone); 

And I can't do:

Code:

EditorUtility.GetPrefabParent(clone); 

Problem is, I have lots of scene objects (gameobjects) that are not prefabbed. I can create prefabs and I can instantiate (off thess prefabs) new gameobjects in place. But then these are not connected to their prefab.

How can I Instantiate a Prefab and Reconnect the resulting Object to t$$anonymous$$s Prefab?

Here is a bit more code to explain what happens (or isn't):

// create the prefab for t$$anonymous$$s transform ... newPrefabPath = prefabPath + Path.DirectorySeparatorChar + _t.gameObject.name + ".prefab"; newPrefab = EditorUtility.CreateEmptyPrefab(newPrefabPath); EditorUtility.ReplacePrefab(_t.gameObject, newPrefab);

             Object prefab = AssetDatabase.LoadAssetAtPath(newPrefabPath, typeof(GameObject));
             GameObject clone = GameObject.Instantiate(prefab) as GameObject;

             // now replace the actual object in the scene with t$$anonymous$$s prefab
             clone.transform.localScale = _t.localScale;
             clone.transform.position = _t.position;
             clone.transform.rotation = _t.rotation;
             clone.transform.parent = _t.parent;
             clone.name = _t.gameObject.name;
             Debug.Log(EditorUtility.ReconnectToLastPrefab(clone));
             EditorUtility.GetPrefabParent(clone);
             GameObject.DestroyImmediate(_t.gameObject);

So what I basically do is creating an empty prefab, replacing the contents of the prefab with an existing gameobject, then load t$$anonymous$$s newly created prefab and instantiate it in the current scene, then set transform values according to the original game object and finally destroy the original game object.
