Using the UPSXML addon. I have a client that has to ship each product seperately, and the UPS shipping costs he is being charged is based on the weight only and doesnt account that there are multiple packages. In the following example he is charging the customer $14.61 but being billed by UPS for $20.14.

(examples)
If he ships 1 package at 9 lbs = shipping costs $14.61


If he ships 2 packages that totals 9 lbs = shipping costs $20.14
includes 1 package at 3 lbs = shipping costs = $9.81
and 1 package at 6 lbs = shipping costs $10.35

Is there a way I can configure this to calculate the shipping on the individaul weights instead of the total weight?
Thanx
