Alerters - Highlight Intersection

Hi,

Trying to highlight the intersection of matching row and column values. I have a Crosstab template where rows contains the same values as the columns (i.e. Row: Red, Yellow, Green, and Column: Yellow, Red, Green). I would like to use an Alerter to change the color of the cell where the values match (i.e. change intersecting cell fill to red when Row:Red = Col:Red). Is this possible?

Thanks in advance.
