adding next previous on product page

We are so frustrated that the Next | Previous links were removed from the product page (debut theme). It is critical for our site to have it. Is there any custom code solution to bring it back?

Please give us your site URL. We can then take a look at your issue.

Keep in mind this is pretty much stock Debut theme. The Next | Previous links were part of the debut theme feature that was on the product detail page and we were told squarespace simply removed that feature. If we can get some code to bring it back, that would be great.
