INA229 to measure temperature

I am basically using INA229 to measure current, voltage, power, and temperature of four 12V 100Ah batteries connected in a series-parallel combination. But before I ordered my sensors I read from the data sheet that it has an integrated temperature sensor, since it serves my purpose I didn't bother to read more. Apparently, when I read it later fully I got to know it can only sense/measure the die temperature of the sensor.

So my question is: Can the sensor be modified (CODE MODIFICATION) to measure/sense the temperature of the battery along with current and voltage? If not, Can a temperature sensor be interfaced to measure/sense temperature? or Should I replace the INA229 completely with another device that helps me measure all three current, voltage, and temperature? (If any please recommend me)

TI's TMP512 and TMP513 perform the same functions but can use external diodes or transistors as temperature sensors. A number of TI products include this feature.
