That link was introduced to me by a fellow board member on the CGC forum. It is not part of the ebay system, but it is a great tool; especially for those powersellers with thousands of feedback
Ebay emailed powersellers a newsletter a few months before the new feedback rating system was slowly integrated and asked for other suggestions on how they could improve the site. I suggested a feature which is similar to the link above, so hopefully they make something like this in the future.
Enjoy everyone.
