How can i exclude exclude a site Section from Taskview

Dear Confluence Pros,

i have a a Confluence Template and i have on One side a list of the Participants of a meeting and a checkbox for every Participant to check who is present.
And in this Protokoll it is possible the we wrote ToDo with the same checkbox.
On a Startpage with all Protokolls i will collect all ToDos/Task from the Sites. But not the not present participant.

How can i exclude a Section from my Pages in the "Task Report Macro" 

Thanks in Advanced
