I have set most of my items with preset weight and dimensions
I have a problems when I have multi item order, that cannot be preset,
I want to make it idiot proof, shipper doesn't care, if a label print, he will ship without entering weight and dimensions, even if it cost me all the profit and ship at loss.
I found that if multiproduct shipment are at zero weight, a label doesn't print,
that force shipper to enter weight then he can print label,
but some shipping company can generate label without having sizes entered.
So I don't have the best rate or the best provider.
Sugestion : add a way to block creating a label if dimensions are all at zero when on “package” ?
