How Do We Select By Group and NOT By Project?

I'm trying to select GSA SER projects by the Group. Is this possible? Thank you!

Also here, please show a screenshot.

Hmm...Sven, let me think about how this might work.

I guess in Project Pane>>Rt Click Menu

Select

By Mask

lemme make it...holdasec please

I guess something like this. 

OK, added it for next update

Thank you, Sven.
