How to set all the sessions logging automaticly? [1]

The "Logging" option only takes effect when you configure the specific session. Now how can I let all the sessions logging automaticly when I log on?
Because I have a lot sessions to maintain, it's too fussy for me.

Program Ver. : Xshell 3.0

Thank you for your comment. You cannot change settings in multiple sessions at once. But, we are considering adding such feature in the future versions.
