Hi, would it be possible to add the shipping/tracking number for regular 1st Class postage to the orders in the same way that it is for "tracked" orders please? I don't need fully tracked, I only need the delivery status, but I need that number synced with Shopify so that Paypal releases my funds when an order is delivered to the customer. It's such a pain to have to enter them all in manually every day. It would be so helpful if this was implemented. Thanks a lot
