Specific Values for Human Height

Is it possible to give a specific value to the height parameter?
I can't find any way to do this so I'm forced to guesstimate the measurements of all the other components of the human model to reach a total height that I want. It would be a lot easier if we could just type in the desired overall height of the model.
