Chan non-linear magnetics

I like the ease with which non-linearity can be defined for inductors and transformers in QSPICE compared to LTspice. Are there any plans to add a non-linear hysteretic core model (e.g., John Chan et la. in IEEE Transactions On Computer-Aided Design, Vol. 10. No. 4, April 1991), or some others means to add hysteresis?
