Integrate WooCommerce shipping with USPS

I am using WooCommerce Shipping and Tax plugin for generating shipping labels and also using the WooCommerce USPS shipping plugin to show the USPS rates to the customers on cart and checkout page.

Now, using this USPS shipping plugin the plugin automatically chooses box sizes according to the product dimension and weights. I want that whatever the box is choosed, that box could also already selected in the shipping label generation.

Does there any extension that provide this functionality or Am I missing any settings?
