I'm trying to assign specific modules to categories in my Newsportal. For example, I would like to assign a poll module on driving habits only in the car category; a poll module on ownership stats in the house category, and so on.

If I create blog content categories, I can do that without any problem. 
I simply assign the module to the desired Menu item link in the page/item section on the right. Using the Newsportal, I can`t figure out how it can be done. Creating menu links with section or categories will not make them show in the menu item links.

So, In a word, can that be done? Thanks.
