AbleCommerce Shopping Cart Software

I currently have the pager controls on my category page that display, "Showing items 31 - 44 of 44" and the boxes below it that link to each page of the results.

I'd like to have the row with the boxes display like "Previous | 1 2 3 | Next" where the previous and next text are links to the previous/next pages of results. Any idea how to do this?

Thanks!
