Change NB Pen setting to constant?

[Ashe]

Hi!
I'm looking for a TM script that can change your pen setting to whichever pen you used last (or specify a pen name in the code for the script to auto-select on every board you visit).
(you need an account to see links) does that, but only for the custom pens. If you use a real NB pen, it will set the setting back to the first custom pen from the script.
Is there any way to do this easily? I don't understand enough code to try and pull it from his script to work with actual pens.

Thanks a lot in advance!
