Shopify multi shipping method issue.

Job ID: 31211742

Budget: $30 – $250 USD

In our Shopify store, products has different shipping methods.
For example, product A has shipping method C, product B has shipping method D.
If I add product A or B to cart individually, then each shipping method displayed. There is no problem.
But If I add product A and B together to cart, then none of C and D is displayed.

What I want to is that to display shipping method C or D in this case.
Is that possible? Please let me know.
