is it possible to calibrate 2 load cells in the yourdyno. I want to swap from a 13 inch to a 9 inch absorber without loosing the calibration for the 13 inch  (2 seperate load cells) if I select load cell 2 for the 9 inch and load cell 1 for the 13 inch can I swap back and forth just by selecting what load cell I am using.
