INA148-Q1: to set the tolerance for offset and Gain on pspice model

Part Number:INA148-Q1

Hi Team

my customer downloaded INA148-Q1 pspice model from TI.com.

he want to set the tolerance for offset and Gain,

but he said there is no feature to set the tolerance for offset and Gain by user.

may I get lib file for him to freely set the tolerance for offset and Gain ?
