One product three (changing) shipping options

Hi

I’m trying to sell with Woocomerce a few products, and every product has three shipping options.

For example 1.Free pickup 2.Flat Rate 3.Express delivery. And every one of those values will have different rates for different products.

So I made a lot of shipping clasess and every product gets the same value(variation) with different clasess.

The problem is that when a product has 3 different variations and each variation has a different shipping class, it sees the product as three products. And I’m interested that it should see it as one product with three shipping options.

Thanks
