Is Stock Picking manual for chained location splitted ?

Hello,

My propose is use one picking list validate 2 time of each sale to customer.
When create packing if set chained location to manual it will create two step validate. In my case,
with the same picking list:
Validate (outgoing) 1. Stock > output
Validate (delivery) 2 . output > Customer

My problem is for the first validation inside the packing list has 2 line of the move( PC1 and PC2) and then after validated the first move it's create 2 delivery orders , and for each order contains only 1 line.

My question is, It should create 1 delivery order that contain 2 line ,right ?

Let me show the case clearly.
1. set stock move chained for output location to customer
- Automatic Move : "Manual Operation"

2. Sale 2 products (Name: SO-001)
- create Sale Order
- Add line PC1 and PC2
- confirm sale order

3. Outgoing Product : Packing create automatic then confirm sale order
Name : Pack-001
Origin : SO-001
Lines : - PC1 | stock > output |
            - PC2 | stock > output |
- then validate packing(all moves to output done)

4.Delivery Order :
it found to delivery orders 2 picking list
(1)===================
 - Name : Pack-001
 - Origin : SO-001
 - Lines : - PC1 | output > customer |
(2)===================
 - Name : Pack-001
 - Origin : SO-001
 - Lines : - PC2 | output > customer |

For this delivery order should create 1 order with 2 line same as outgoing packing ?

Anyway I try manual create outgoing packing list manually to see who it show.
1. Outgoing Product :
Name : Pack-002
Lines : - PC1 | stock > output |
            - PC2 | stock > output |
2. Delivery Order :
Name : Pack-002
Lines : - PC1 | stock > output |
            - PC2 | stock > output |
It work correctly

Thanks,
