Can a customer choose two shipping options for different products in their cart?

I already have two locations in my shop. I have activated multi-origin shipping. Here is my setup:

1. Product A is only available in Location X
2. Product B is available in Location Y and Location X
3. Location X only has "Standard" shipping
4. Location Y has both "Standard" and "Expedited" shipping

If my customer wants to buy B and A, how can I allow them to expedite shipping for B and still let them buy A with standard shipping?

Right now if my customers have a mixed cart, then Shopify only makes the mutual shipping options available at checkout.
