Crystal Reports: suppress value and display a different value

I am not entirely sure if this is possible, but I am working on a report that has a cross-tab to show people (row), courses (column), and the percentage of the course completion for each person. The value for the completion percentage is good, but the total percentage number at the end of the column is off.

So I want to suppress what is currently showing under the Total column, and display something else (a different value from a different formula). Is this possible?
