octaves within a chord

[Rick Kimpel]

Jay,

I recently came across your octaves script from back in 2008. I was wondering if there was any way to make it only octavate the top (or bottom) note in a chord? I arrange for handbells, and this is a common technique. I was going to try to do it myself, but I can't get the original script to work in version 2.18.

I was also going to try something based on Gianmaria's and Aaron's work with parallel thirds, but I couldn't get that script to work in 2.18 either. Might be time to upgrade. :\ 

Thanks,

Rick
