[GIS] How to label adjacent pages in data driven pages

arcgis-10.1data-driven-pageslabelingmatch-lines

I'm trying to create a mapbook using ArcGIS 10.1 data driven pages. Its quite large and I want to create match lines or labels so that if you are looking at a page, there is text/labels showing you which page is adjacent to the top, bottom, left, right.

If I remember, correctly, this option was part of the data driven pages toolbar in 10.0, but it doesn't seem to be there now?
