Turning off the Reservation Linking

Q: How do I turn off the linked reservation stuff?  We don't want any linking, since making them Synchronized causes more work for us later to separate them, but we keep forgetting to uncheck the "Synchronize with" box.

A: In the New Reservations dialog, click the "Linking" button.  Select "Not linked at all", and check the box "Save the selected linking mode".  Now they won't be linked unless you force the check boxes.
