Remove weekends from the report results

Hi All,

I have a Queue Activity report that is a part of our Managers Dashboard.

This standard report with a chart shows queue activity for the last 14 days. It consists of a chart and 2 columns:

Interval: date_group(inc_performance.time_start, $date_grp_param)

Incidents: count( distinct inc_performance.i_id )

is there any way to remove weekends from this report?

Thanks!
