Modified Masing Hysteresis Criteria

I want to change the Masing unloading-reloading branches of a hyperbolic backbone curve. How can I do this in OpenSees. I am writing the code in C++ but where and how can I implement it? There are some useful documents about new materials and new elements but what about new hysteresis?
