SKU order on Invoice by Fulfillment not matching SKU Order on pick/pack

In advanced Sales order when you choose to invoice via fulfillment, whatever order the SKU's are shown in on the pick/pack that is the order they need to be shown in on the invoice as well, they should match. instead they are being shown in alphabetical order by description. meaning the packing slip and invoice you send to the customer do not match, increasing human error in receiving the order and creating confusion.
