Different Shipping and Billing Addresses

I am configuring v3.10 for a B2B site.  Some of our customers have different billing and shipping addresses.  During the customer registration process a customer can only enter a single address.  I see in the Admin area that we can add more addresses, but I can't find a way to designate an address as a specific billing or shipping address.

Is there any configuration option that will allow me to do this?  Or am I going to have to customize nopCommerce to do what I what?  I see what looks like support for a separate shipping and billing address in the Customer table (Billing Address_Id and ShippingAddress_Id), but I don't see how to make use of them.

It's not available out of the box.

Billing Address_Id and ShippingAddress_Id are set by the system during the checkout process so that they can be put on the Order record.

Thanks for letting me know.  I'll just add this to my list of customizations.
