@RonRosenfeld Sorry about the delay in replying. Yesterday was crazy busy, and then I decided to do some more investigation before posting. I have set up a demo workbook that I'll upload, and I'm in the middle of typing up a comprehensive explanation. (Would make a great blog post! If I had actually blogged, that is ;-) ). I have to go do some other stuff right now, though. Will finish up later today.
