Substitution on PO - Update entire order

If a product is substituted on a PO, then it should record on the order (showing customer facing note), and all production notes/files should also be updated.

if a shirt was changed colour, or size (even sku if needed), then production knows that they have the correct products to produce, and not question, why they are either missing an item or have an extra.

The substituted product would be accurate on the production worksheet for what is actually received.
