Is it possible to move the header from within the group, to outside the group at the top of the grid.

Basically I'm having a problem where the user can see the summary values in the group headers, but has no clue what columns the values correspond to. Additionally, when multiple groups are expanded, the column headers are redundant and take up space.

I'm not sure if this is possible- I've scoured the forums and couldn't find an answer. If not, I'd like to formally request the feature, thank you!
