Help About Woocommerce Shipping

Hi,

Is there a way to set one shipping cost charge for specific product in cart no matter how many times the product has been added to the cart?

The Issue is, I have set up Length, Width, Height and Weight for each variation so when I add any of the variations to the cart, the shipping cost adds up. But I want the shipping cost to be the same for the product no matter how many times I add the specific product.

However if I set up flat rate shipping, it shows up at the shipping selection area and when other products are added, the shipping costs show but customer will select the flat rate for all products added and in that case, I will lose for customers not paying for shipping for other products.

What is the solution please?
