I want to perform this:

- "P1" is a storable product 
- "P2" is a storable product
- "P1P2 Kit" is a consumable product and a group of 1.0 P1 and 1.0 P2 (i'm defining it using the Kit BoM)
- "MP" which is storable and manufactured product

I'm tracking P1, P2 and MP by serial numbers.
I want to automatically make purchase order for P1P2 Kit once i try to manufacture MP and there's not ennough P1 and P2 in the inventory.

 I'm using the MTO routing for P1P2 Kit but once the purchase ordering is being created, it contains multiple lines one for each BoM.

However when i manually make a purchase order, i can specify in the purchase order that it takes only one line (P1P2 Kit) and only when it comes to the receipt order that i have to specify the serial number of the BoM.

My doubt is to make sure the BoM are not splitted on the manufacturing order, but still need to track the items in the manufacturing order, is it possible to do such thing ?
