SSE How to load temporary object via script

[s4e8]

Game.GetFormEx(), Game.GetFormFromFile(), and "FormList.GetAt() as ObjectReference" don't work for temporary object reference, if the cell is detached, and the target object hasn't loaded. How can I force loading this formid, or force attach the Cell?
