Setting Up Pre-Mill in MV

I'm looking into setting up Pre-Mill in MV for banding. I see that you can add a pre-mill value to the edge band material in the material library. Putting in a value there didn't work. I'm assuming I have do something to my tool files as well. 

Does anyone know of an MV document that can give me guidance on how to get this setup?
