Hi, I have a question concerning shipping rate per product.
I already added two shipping methods using rate per product and configured it. As I have two options (regular package shipped by company A and oversized packages who have to shipped by another company B because of dimension), I need to set the shipping rate per product and not per weight.
But where or how can I add one of the shipping methods to single products? Cannot find anything on single product layout and was looking in all settings as well

but cannot find it, either in documentation?!
Thanks and stay safe!
