To add more inputs you simply daisy chain the output of one into the input of the other.  Normally you would take the first seven inputs and output them into input 1 of the second one.  Adjust the starting points to match.  Since the first position starts at Zero for both of them then the first 7CCR runs from say 0-50%.  At that point you then set the start of the Second 7CCR to be 50% and work your way up the stack.  Feeding the same Factor into both results in the Second 7CCR outputting input 1 which is being fed by the First 7CCR and its 7 inputs.  on the Rework I was thinking about upping the number of inputs for a couple of reasons.  If 10 seems like a good number I will look at that.
