To be able to make informed decisions in web view after merging records, please bring over the properties that exist on addresses in database view. For that matter, all fields that have properties in database view need to be transferred to webview. Being able to tell which address to make primary in web view is almost impossible because there is not enough information. 'Starts' is not enough information. Also, where are the import IDs in webview? As a database admin, import IDs are extremely important.
