Allow addition of Address while creating Site users

At present when you create a user you are required to add the details and then save the user in order to get an Address book option so that the address can be added. It would be great if we can add all the details together so that we can save everything together like it is possible on Storefront account creation.

We have checked the import function and found that the import template shows columns to add address and I believe this will allow us to import the users with at least 1 address.

It would be helpful to have all the information together so that we can add it all together and avoid few extra clicks.
