In some cases, a site user ships to many different addresses over time. It would be helpful in these cases if the site user could enter a ship to address but not add the address to their address book. This would prevent the address book for getting many addresses, most of which are used just once.
Yes, please!
Use Case Example: We work with a couple recruiting teams that are going to various events throughout the year - most of which will never be shipped to again. It would be nice to have an option on the new address setup that the user could unselect if not planning to use the address again.
