When splitting an order, the separate shipments should include the weight

[tech1]

We have a Shopify storefront with orders that require individual line items to be broken out. The "Split Ship Actions" allows for this, but the resulting Shipment 2 always has an empty weight value. The "main" order of Shipment 1 weirdly has it's weight reduced to reflect the removal of the product that was removed, but the new Shipment 2 has no weight and cannot calculate freight. It has to be manually entered and we're dealing with thousands of orders. This should be automatically calculated. Thank you!
