Product Spare Parts

It would be great if we could associate Products with Spare Parts. We often find if a customer breaks a part or requires a new one - we need to create the part in storefeeder to process - but if at the point of onboarding, we could create "parts" that could then be itemised - under the main product. We trialed using kits but as it isn't part of the routine product - it doesn't really work. It would almost just be a way to link the product to another so that there are a group of products associated with a main product. This way our team can see what parts are available to supply a customer.
