How to select scout

Hi all

I have a problem with region selection.
When I use one atlas and try to select multiple regions from the picture I can't do it.
I can select multiple regions by hold ctrl from keyboard and select regions from scout menu but since the area are not readable well, selecting from the picture is easier but from the picture, I can just select one region and ctrl doesn't work.
I would like to select multiple regions and use copy selected regions.
would you please let me know how can I select them from picture?

Cheers,
Hamed
