Caleb Burks on "[Plugin: WooCommerce] Shipping question - package size/quantity"

We are using WP with Woocommerce, selling a product that is sold by the pound, and we use UPS for shipping exclusively. For shipping, we are using 5 different sized boxes depending on the quantity of the product being sold. For example, 1-3 pounds uses box A, 4-7 pounds uses box B, etc.

Is it possible to set this up without using the flat-rate option? As the boxes increase in size, the quantity range grows - the largest box is used for 26-40 pounds. Obviously, the shipping charges for 26 pounds are considerable less than 40 pounds, and we don't want to charge our customers the 40 pound rate for 26 pounds.

Basically, we would like to set it up like this:
Qty: 1, weight 1, dimensions 6 x 6 x 6
Qty: 2, weight 2, dimensions 6 x 6 x 6
Qty: 3, weight 3, dimensions 6 x 6 x 6
Qty: 4, weight 4, dimensions 12 x 9 x 4
Qty: 5, weight 5, dimensions 12 x 9 x 4
etc.

If someone can point me in the right direction, either through Woo/WP functionality or through the use of a plugin, I'd greatly appreciate it.

Thanks!
