Would it be possible to make it so the "Package Quantity" field is related to the catalog, not SKU? So when shipping rates are calculated it will assume that products in the same catalog will be packaged together? Based on how I understand the wording: "For a package containing only this product, how many are in it?", Ubercart will only assume that products that have the same SKU will go in a box together, if you set this field to more than 1. I would like it to work so that it assumes any product that has the catalog term "T-Shirt" or "Jeans" or even a more broad term like "Apparel" will go together in one box and other catalog terms will go in another. If i am correct, then if a customer chooses to buy two different t-shirts ubercart will calculate shipping thinking that these items will be in 2 different boxes. Anyone know how to make this work?
