Is there any way to have the Scanner and Camera Wizard only transfer pictures that haven't been transferred yet? I mean automatically without having to click anything?

In other words, I have the Wizard set to save all pictures to dated subfolders. Without selecting the "Delete pictures from camera after saving them" option,
I'd like to have the Wizard automatically save only pictures that it doesn't have yet when I attach the camera to the PC. And not bug me with dialogs.

If not possible, can anyone recommend camera software that will do this? Free would be nice but it doesn't have to be. Thanks!
