How can I export shipping data including box size, weight, and cost?

These tools are great, but I wished it included the total weight of just the products in the box.

I’m beginning to use a new shipping service that is based on weight, and knowing this would give me a better idea of the range of product weights that would fit the service used. For example, there is a flat fee for packages under 0.5 lbs, but I need to know if a product weight of 0.4 lbs should be the maximum weight for this service.

Sometimes the box weight can be wrong due to the size of the product and the amount of packing material used.
