BOM with Multi-Inventory

I just purchased BOM and Multi-inventory add-on.

I have 10 products with its own inventory QTY and want to sell to 5 difference places (may be different price).
Therefore, I am planning:
1. Set product as “product parts”.
2. Create “simple product” and using “product part”.

Ideally, I was hoping:
– The “Simple Product” can directly use the inventory QTY of “product part”, but I do not know how to link them.

I am wondering if it is possible to let more than one “Simple product” share one “product part” inventory QTY.`
