You'd need a multi-state flow where the core code did the 'add' but that doesn't do everything until the driver assigns an ID to the restrack object.. non-id objects would live in some purgatory where they can't be searched, but otherwise work OK. This is possibly a simpler patch flow process than updating every driver at once in a giant single patch.. Jason
