Shipping methods by Class

Hello,

Firstly, thanks for so great plugin.

We actually use different shipping methods for different product Class, and product are classified by weight or dimensions, so that we can use most right shipping lines.
Please check this screenshot at https://woocommerce.com/wp-content/uploads/2013/04/WooCommerce-Shipping-Classes-Product-Shipping-Class.png

Here are the details of product shipping class:

For example, here are product classes on our site:

1.Small size product
2.Medium size product
3.large size product

So, there are usually at least three shipping methods for different product shipping class.

It would be great if you can make it support setting estimate delivery day by shipping class please.

Thanks and have a nice day.

Thanks
