Changing column headings based on drill down toggle

[goofaholix]

I have a drill down report that has column headings for group 1 data in the report header. When the user drills down to the details I would like to change the column headings so that they correspond to the details group.

I've tried to create to column heading rows and toggle their visibility with the drill down toggle field but get the error message "Toggle items must be text boxes that share the same scope as the hidden item or are in a scope that contains the hidden item, and cannot be contained within the current report item unless current grouping scope has a Parent."

Is there any way of doing this?

Thanks.
