Thank you John, that should definitely do the trick! Furthermore, I believe that this will help me research the available resources more effectively in the future -- instead of researching a specific problem (e.g., "invert Likert-Scale items"), I might try starting out with a more general problem (like "recode values") in order to work my way towards a solution.
