Unfortunately it is not fixed for the Data Services Wizard. We are currently in the process of replacing the wizard itself with a service generation add-in and we are going to implement this and many other necessary features there. For the time being you can proceed with the practice of checking-out the items you need to change.
Kindly let us know if you have any other questions or you need further clarifications.
