Currently, when I set free shipping for bundle/combo products, the app still considers their weight or shipping cost if other normal products are added to the cart.

What I need is:

If the cart has only a bundle → free shipping should apply.

If the cart has a bundle + normal products → shipping should only be charged for the normal products. The bundle weight/price should be ignored in shipping calculation.

This way, bundles always remain free shipping, but do not interfere with the shipping rules of regular products.

This feature will help merchants like me who offer special free shipping bundles but still want to charge shipping for regular products in mixed carts.
