I am trying to use button sets, and scroll between them... but my new button sets start completely blank... Can I make a new button set a duplicate of what already exists, so I am really just adding a few new buttons to the end?

Not directly but using the scripting command toolbar you can export and import button sets via clipboard.

You can use the script here viewtopic.php?f=7&t=22666 to build, modify, save and load toolbars. It's been for the most part completely replaced by Don latest toolbar changes. It works strictly by building and saving of toolbars, as Don mentioned, to a toolbar file(txt) using SC toolbar(). You'll have to keep in mind that the toolbar would have to be "loaded" from the script's menu and you would want to be in a new or different toolbar set # like set 2, 3, or 4. I haven't updated the script to reflect multiple XY built-in toolbars and probably won't.
