Adding customer sidebar to all category / archive pages

Hey guys

I am using the whitelight theme from woothemes. I need help setting up the theme to display archives and categories sidebars on all category and archive pages. I know I can manually create customer sidebars for the different categories and add these widgets but as the blog expands this wouldn’t make much sense to do everytime.

I’m not sure how to go about doing this.

I hope its clear what I need.

Any help would be appreciated.
