Wow. I honestly didn't expect an actual working answer so soon. I was going to use sub folders for each toon simply for organization. I was also drawing from the way that the mastermind bind files were working, a sub folder for each type of mastermind as it binds using powexec_name for the different levels of summons. I realize now that a single text file is all that would be needed for each toon so keeping them in the default directory would be fine.
I did like the popup menu idea, I'll admit I never would have thought of that, but not all of my toons are setup the same way.
Thanks to you both for your excellently helpful suggestions.
