Add superscript to specific cell in PROC REPORT

Hello:

I need some help figuring out how to add a superscript to a specific cell in a PROC REPORT table. It has nothing to do with whether or not certain conditions are met (like add a superscript if value <0). I need to add a superscript to a specific row/column combination.

Let's say I have a 5 x 5 table and I want to add a superscript to the 4th row, 5th column. I do not want to actually type in any specific values (such as if value=....then add asterisk) because the values may change. However, I will ALWAYS want to place an asterisk in this specific cell.

Any suggestions?
