Sort by categories on special page

Hello,

is posible to sort the products of the "specials" page by categories? I mean, if you have in your shop the subcategories trousers, t-shirts etc. is posible to sort the products that are "specials" by categories in the special.tpl page in order to be easier to the customers to see of what type are the products?

So:

t-shirt t-shirt t-shirt blazers, blazers, blazers etc. haha

Thank you!!
