Counting totals in static group by

Hi,
I have a grid app that uses static group by (see attached image). I want to add after each grouped rows a line with the summary containing the total of rows count per each group. Is this possible to do it? Scriptcase only allows to summarize by sum, average and other functions, but not only by count.
Thanks,

Dani
