Add to cart botton in Catagories product lists

[gkt]

How do I or is it possible to add a "Add to Cart" bottom to the categories lists, either to the side, above or below the "Product details" Button, saving our customers having to click on the product details button, to add a simple product to the cart.

Thank you
Glenn
