Filter to specific column

Content

Hi all,

I am interesting to know how to set filter only to specific column and not to the whole report as usual.

I am based on report;

\Public Reports\Service\Queue Reports\Queue Activity

The idea is to connect Tables: inc_performance > incidents > threads (all by inner join) and to individualized column "Responses" ( sum( inc_performance.action_cnt ) ) to show only responses made by the user ( threads.entry_type = 'Staff Account' ),

Any idea how it could be feasible?

Thanks .
