Webform CiviCRM "fields not to autopopulate" feature

A small improvement for webform civicrm.

The scenario we have is that the client want to be able to enter a contact ID to renew the contact’s membership. The form the need to show the contact’s name and ask for billing/other address, however, we don’t want to show the existing billing address (potentially other addresses either) to people. It looks like there isn’t a way to do this at the moment.

As currently you have the "fields to hide” for existing contact, we are thinking to also a have a multiselect of “fields not to autopopulate” which can control what data to bring back to the webform.
