In Database View, whenever we would add a Solicit Code of "Do Not Mail", we would also add a new blank address as their preferred address. In webview, I tried to add a blank address, but it will not let me save. Unfortunately, this leaves the address that they specifically requested that we do not mail as a "preferred address". Obviously, we plan to use the solicit codes, and "no valid addresses" tag, but it would be nice if there was a way to add a blank address so it is not visible on the record.
