So I had an idea but there might a better way to achieve this.  What I would really like to be able to put data into the Rhino file that Grasshopper would see.  This way I could use that same grasshopper definition across multiple files.  For instance I could put something like Height = 12 in the Rhino file either as text or maybe DocumentUserText.  Then you could set up a Pipeline to read that info.  This way I could have 1 file with H=6 and one with 12 and the definition would react accordingly.  Maybe there is a way to already to this that I am overlooking.
