Need help adding a button to home page

Hi. I need to add under the Advance Scrollers I have in Home Page a button with a link to each department of products showed.

Example, I have a Combo department. I am showing only 30 in the Advance Scroller but if people would like to see all of them I would need to provide a button to the Combo Department.

I am not looking to modify the Advance Scroller function. I would like to add the button in a different Block under the Advance Scroller block.
