Brightslide has soooo many features, and I use many of them almost daily. This is just one feature that fills a gap in PowerPoint’s formatting features, and has some really nifty hidden functionality.
Here are the 2 webpages for Brightslide. The first is where you can download the installer, and the second is an info page that covers almost 80 of the features.
And, Brightslide is one of the few productivity PowerPoint add-ins that has both Windows and Mac versions!
