Hi @RLietz,
I have donned my blue cape and have personally written this for you in Python. It does what you ask (and in mm 
).
It’s not fool proof as unfortunately I am sitting next to my Kryptonite cactus 
given to me by my best pal Lexicon Luther and my superpowers have been weakened by it’s presence. Also, I have a busy day ahead so had to be super quick as I have to save Kittens from trees and stuff.

Hope this helps you out with your forays in Dynamo…
Cheeeers,
Dan
