Mario tweeted earlier today that he's updated his utilities for Revit 2012. It's good timing, I was just going to ask him about his Sheet Set Manager too! It allows you to update sheet list schedule from Excel data or vice versa.
He started Whitefeet some years ago and returned to doting on it after departing HOK and joining Perkins & Will. Unfortunately for us, his full time gig with Perkins and Will means he's got little or no time to dote on "the feet" again.
Worth checking out his tools, see if you like them!
