Rigging: Control Rig Cast or Promote variables?

[Sean3Dmonkey (Cocoflakes)]

I have a Control Rig controller set to integer. The Controller integer slides between 0-15.

Question: Is there any way to “cast” or “promote” the controller integer to variable so I can drive scalar U and scalar V parameters in a material instance?
