Hi clac ,
Thanks for your post.
Unfortunately, that isn't possible. The product items option is only available when BOM Stock control is disabled.
The only way to work with the produce items option and BOM Stock control together is when also using ATUM Multi-Inventory. You can read how they would work together in this article (Scenarios 2 and 3). Maybe Scenario 2 will fit your needs.
Best Regards,
José Andrés
