Chart in groups footer of SRB

Hi Ocke,
In OOo Hu forum I met one issue, which I can solve, but may be an 
enhancement for SRB.

The report developer get the task count copies printed out in each 
printer (BW/color) and by persons.

He want to use charts in Grouping footers to show result day by day 
basis, now with SRB we can set chart source separately from whole report 
source, but that is not good for this purpose.

I think this is not solvable now, needs an enhancement.

Thanks,
Zoltan
