prefab of gameobject with several child objects referring to another prefab

I have a complex gameobject with several child gameobjects which are based on the same prefab. When I create a new prefab from the complex object the children lose the prefab connection to the original prefab and refers to the individual child in the new prefab.

Visual representation:

-------------------
first
-------------------
1. Original prefab

2. Complex gameobject
- Child object 1 - refering to 1
- Child object 2 - referring to 1

-------------------
second
-------------------
1. Original prefab
2. Complex prefab based on complex gameobject
- 3 - child prefab 1
- 4 - child prefab 2

5 - Complex prefab instantiation
- 6 - child object 1 - referring to 3
- 7 - child object 2 - referring to 4

Is there a way to keep the many-to-one connection when using prefabs/importing/exporting or is there another way of doing this?

 

As far as i am aware you can not have nested prefabs, its on the requested features list:

Thanks, too bad. Any tips to ways of keeping prefab connections while exporting/importing?
