Is group possible in PRD when using CGG?

Hi,
I have 2 depending graphs in CDE - in 1st one I can set parameter via firechange for the 2nd graph. Is it possible in PRD to make the 2nd graph using group function(URL from CGG)? Output should be 1st graph plus 2nd graph for each category(parameter in 1st graph in CDE).

Thanks a lot for your tips.
