B2B Portal should allow customers to toggle shipping addresses

Requesting please add the functionality for customers to choose a billing and shipping address from their Portal customer record.

Testing the B2B Portal trial. Created 5 distinct shipping addresses for my mock company and one billing address. From the Customer Portal, in the Checkout process, only one address will show for billing and only one populates for shipping. User must manually re-key an address if they want a different billing and/or shipping address. Have verified that the additional addresses show under the user profile in Portal, but the shipping and billing addresses cannot be toggled to addresses associated to the customer record. Portal just picks one for the Checkout and then users have to re-key to change that.
