Cazuela Categories Pages Layout

Hi,
First off, love the theme. Thanks.

Secondly, I would like to change the default layout option for the categories pages from full screen to having my sidebar with its widgets on the right hand side. I can do this easily enough for posts but cannot figure out how to modify this for the categories and tags pages that are automatically generated.

Is it possible to modify the layout of the tags and categories pages?

Thanks!

Chris
