Has anybody implemented a solution for the following use case: I want to track Inventory of an Pizza-Ingredient. So for example I made a Bill of Materials for my standard Pizza.  Now it happens, that I have to buy raw materials like Olive-oil in different packages/presentations/sizes (e.g. 1L bottles vs 1,3l bottles, depending on what I get). My question is If there is a chance to join all my olive oil products to one group/sourcing/intermediate product pool. I understand I could set up a BOM for each possible bottle variation (If there is 1,3 bottled olive oil, take BOM1, if not take bom 2 for other olive oil product, etc).  But I would rather need a virtual olive oil tank like an intermediate product joining all existing raw products into one resource, because I have like 80 different Pizzas and do not want to create 80 new boms each time one of my provider changes olive-out package size.
