bq20z45 - Is there an Undertemp charge threshold or similar parameter? (creating a low-temp charge profile)

using the bq20z45, I am trying to create this behavior in my temperature v charging profile:

temperature drops below 0C -> charge current=500 mA

temperature continues to drop below -10C -> charge current =0 or charge inhibit mode

temperature rises to between -10C and 0C -> stay in charge current =0 or charge inhibit mode

temperature rises to above 2C -> charge current =500mA

This is similar to the behavior of the Overtemp Charge Threshold and Overtemp Charge Recovery parameters.  It is hysteretic in nature.  I want to have that same behavior at low temperature.

Using the Temperature Hysteresis parameter is NOT the answer - I am already using a 2C hysteresis in the transitions between temperature ranges (note that in my example).  That works the way I want and I don't think I can change it, unless it is range-dependent somehow..
