Custom calculation - z scores

Custom calculation - z scores

Instead of reporting merely raw totals, is it possible for an instructor to modify the settings so as to show a custom calculation in addition to raw totals? The one I have in mind is a z-score:

\[ z=\frac{x-\bar{x}}{\sigma} \]

calculated for the students over each activity, and then cumulatively.
