Hi Delaunay, 

It is posible, to do so lets say you have parent location WH with 2 childs: Stock, and Stock2.

To receive 10 units of product A lets say 5 on Stock and 5 on Stock2 you have to follow those steps:

1) Activate Storage Locations on Inventory Settings:

2) Create a Receipt and set the Destination Location with WH ( the parent ) value:

3) Add product A  and click in the burguer icon menu:

4) Add 2 lines: 1 to Stock and the other one to Stock2 (if it doesnt exist you can create it from the menu itself, then edit 5 units for each line and confirm:

5)  Go to bar code and you will see 2 lines to process.

I hope that to be helpful for you.
