Yes, you did, Bill... unfortunately, my pz2 files (those created by Parmatic) don't seem to load properly into the figure (I think I mentioned this in another thread). That's kinda why I was looking in this direction.
I'll have another go and let you know how I go. I might try running P-Updater at the outset (puts the group Other in place) and then load the ordered list from the pz2.

But, on the .sort() thingie, would that have been the right approach IF sorting it works? I've been poring over the documentation for Dict, but dictionary methods do not seem to include this one.
