Can you flank the main window with the smaller ones?

Hello,
New user and quite possibly missing something obvious...
Is there a way to create a layout with the main window center and the other clients on both the left and right ?
Thanks for any help.

One a window layout has been created, you can edit it however you like under the Window Layouts node (select Regions in the layout).
The Wizard Layout generator is fixed in terms of what you can do.
