Is it possible to compensate the gain drift of the AD8421 with a resistor of known drift in ppm/°C ?

We use the AD8421 instrumentation amplifier with a bridge. The noise is excellent, but the temperature drift of the gain is far too high. In the spec it es mentioned that for G > 1 max drift is max -50ppm/°C. Do you provide or do you have references for a resistor matching the drift of the internal resistors in order to reduce the gain drift ?
