How to offset the temperature range on a AD7793

I am using an AD7793 to measure a thermocouple. I am using Vbias and a gain of 64. This gives me an approximate range for a T-type thermopcouple of +/-357°C. I would like to extend the positive range to 450°C without changing the gain of the ADC, I only need to measure down to -150°C. What would be the best way to adjust the range?
