Document-specific Item Group

Hello,

We are implementing ERPNext in our manufacturing company. We do injection molding and I wanted a way to link our “mold” to the Work Order, Stock Entry, Job Card, and Quality Inspection documents. This is the scenario:

I have created an item for all our “molds”. For example: “Mold A”, “Mold B”, “Mold C”. I have other items as well for which I have created an item master. Say “Phone”, “Charger”, “Product 1”, Product 2", Product 3", … and so on. I have created an item group called “Molds & Dies” and I have assigned it only to “Mold A”, “Mold B”, “Mold C”.

I want to add a field in Work Order, Stock Entry, Job Card, and Quality Inspection documents labeled “Select Mold”. This list should only show the items that are assigned to the “Molds & Dies” item group. Is there any way to achieve this?
