Can I manipulate my report group header with VBA?

Hi All

I have a report that runs nicely.

I want to give my users the option of grouping the report.

I would like to use the same report object for both to ease
maintenance.

Therefore I would like to be able to tell my report via VBA to group
and display a preconfigured group header when this option is selected.
Otherwise I want no grouping and no group header to be displayed.

Is this possible?

Cheers for any ideas,
Chrisso
