Change to ODB/SPO sharing dialog specific people option

We'd REALLY like to have this default to "People with existing access" in SP. It is messing with our preferred approach in SharePoint of keeping specific user assignment in security to a minimum. We cannot convince our users with permissions that every time they want to send a file link, they need to change the link type, and we end up with people who already have access via group membership now having specific named access.
