Combined Shipping – Multiple Products

I am trying to figure out a way to more easily combine shipping. Here’s an example:

Lets say there are 6 different items:
1 – Nike Sweatshirt (shipping class “sweats”)
2 – Reebok Sweatshirt (shipping class “sweats”)
3 – Nike Shirt (shipping class “shirts”)
4 – Reebok Shirt (shipping class “shirts”)
5 – Nike Shoes (shipping class “shoes”)
6 – Nike Socks (shipping class “socks”)

If someone orders a nike sweatshirt and a reebok sweatshirt, WooCommerce combines them.
If someone orders a nike sweatshirt and a nike shirt, WooCommerce charges both shipping.

First question…is is possible to have WooCommerce only charge one shipping class like it will only charge the larger of the two so if someone buys a shirt and a sweatshirt it only charges the sweatshirt shipping?

Second question, is is also possible to only combine some shipping classes. Like if you order the shoes, it will combine socks for one cost (because they can be shipped together) but it won’t combine shoes and shirts or shoes and sweats?

Hope that makes sense. Thanks.
