product subcategories

How do I get the product subcategories out of the product Display Module but still keep them in the category listing module?

When "SOURS" is clicked, the category listing menu expands down and it displays its subcategories below it in the category listing module(green) and in the content module(teal). I want it to display only in the category listing module. Ideally it would be a separate column to the right (orange) instead of making the category listing module expand. kind of like the sub categories in futureshop.ca's "shop by department". www.futureshop.ca/en-ca/home.aspx#

So:
1. remove second instance of subcategory menu

and hopefully:

2. change it to separate column like future shop

Thanks Nicolas! You've been a great help with all my questions.
