Currently the default sync option is set to "Email" when manually importing into a flexible database. It would be beneficial to allow the client to set the preferred default sync option. This would lower the risk of importing duplicates into a flexible database for clients that may use other fields to sync.(i.e CustomerID). Currently the user needs to uncheck the email field and check the preferred field. While this is fairly simple task, clients that perform hundreds of manual imports are at risk of creating duplicates due to user error. This change would virtually eliminate such a risk.
