Category Discription under the products?

Is it possible to 'place' the category discription under the products?

I want to place a little Wiki with the products, but i cannot do this with a module, because then the article/module is showing under every category. (picture 1)
(i cannot make a selection for one category, an cannot make an joomla menu with hikashop

So now i want to place the text in the category discription, but is is to much for above the products. (Its about the products in the first place) (picture 2)

Is there a way to put the category discription under?
