Tweentyfourteen fullwidth

Hello,

the theme ” twentyfourteen ” there is a bar on the right by default.
it is possible to
fullwidth choose when creating a page.
my question.
Is it possible that the default pages are in fullwidth and if desired when creating a page one chooses to add the bar right?

Because I use wpcatalogue .
So for the pages it generates it would fullwidth .

Thank you for help
