So, imagine we have a product like a screw that is used in many BOMs, so when we access the product.template form view we see: Used in 15.

When I click on the Used in smart button it then show me the 15 different boms, and there is the option to show extra info: quantity and units. But those are the quantity and units for the production of the bom, not the consumtion of the screw. 

I would like to see (for example) 16 uts (that would be the amount of screws consumed on bom 1) from that same view. 

Has anyone done this before? I've searched a lot to no avail and even started doing it myself, but I'm stuck finding the relation between the manufacturing line and the product.

Any advice is appreciaited. I'm using Odoo 15 CE, but I think this is a general question.
