Are there any plans to expand the ‘set shipping’ options? USPS charges shipping based on type of pkg (box, flat envelope, soft pkg, etc.), size, and weight, as well as flat, yet neither of these options are available for me, as it relates to accurate postage. Why? I can not set accurate, competitive shipping rates either of these 2 rigid ways. One way, I lose potentially quite a bit. The other way, the customer does.
