In RE Connect, when data is pulled in from WH's Core, you can review all the information being pulled in individually, but you can only accept the proposed changes in bulk. Users should have the ability to reject changes to a record on an individual basis.
Yes this would also prevent the system from adding a new addres every single day when there's been no address change. I have a ridiculous amount of duplicate addresses in Re and it screws up my mailings every time!
