I have been searching for this as well. I upgraded to Quickbooks Premier for work and I'm surprised with the lack of features you would think would be standard.  I am in the same situation as you. We have multiple different line items so we need to know the total in a package to be able to make sure the shipment is whole.  I don't want to pay again to upgrade to another Quickbooks that has it as upon Googling, Premier seemed to be made for businesses.  I'll be crossing my fingers that the feature becomes available.
