Move column headers inside the GridView group

[Charles]

I would like move the columns from the top of the grid to inside the group, i.e. where the group header would be. The reason I would like to do this is so that I can customize the column header text based on the group.

I know this might sound a bit crazy but the reason I would like to do this is because I am having to work with a data structure that has the following columns:
 - Group Type, Name, Col1, Col2, ... Col10

So Col1 might be "Make of Car" if the Group Type is "Man" but called "Toy" if the Group Type is "Boy". So the columns headers need to be different for each group.

Is it possible to do this?

Is someone able to let me know if this is possible?
