In ABAP coding for ALV reports (not for Web DynPro), can I attach a sort property to one column based on the value of another column?

Basically, I have a column showing values mean-Median-Max. I defined another column where I extract the value of median from former column. Now, when someone tries to sort the former column, I want it to sort by the value extracted in a later column.

I know this is possible when I use ALV grid in Web DynPro. But my question is whether this is achievable in a list displayed through ABAP report program?

Thanks.
