Allow updating the product location after order import from Shopify

To allow updating the product location after order import from Shopify Example: 2 SKUs are assigned the Channels Shopify location but then 1 ends up as out of stock at the Channels fulfilment locations. Within Shopify we can split the order and send the SKU with no stock via a different fulfilment method and leave the SKU with stock on the Channels location. If this updated in Channels then we could still successfully send part of that order with Stock to the warehouse as it would no longer be trying to send both the in stock and out of stock SKUs within the order.
