Is it possible to identify the heating point when several PTC thermistors are connected?

It is not possible to identify the heating point when several PTC thermistors are connected.

The TCTH0 Series IC supplies a small amount of constant current to PTC thermistor, detects changes in resistance/temperature, and generates a FLAG (Hi/Low).
When several PTC thermistors are connected, the change in the combined resistance of several PTC thermistors is detected, making it impossible to identify the specific heat generation point.
