Add Shipping Classes to Products

For LTL (Freight) shipping services you need to specify the shipping class. As of now the system only allows you to set up a global shipping class for ALL the items - which is not very useful.

Can the shipping class be added to the product profile instead? This way the shipping class is passed from the item instead of from the Global settings.

Because there can be multiple items with different classes, the way it works in real life for freight quotes is that you use the highest class, so a simple math calculation can pass the highest shipping class to the shipping calculator in case this happens.

Shipping will be much more accurate than what currently the system offers.
