you can't. map-to-output is a convenience helper because it's the prime use-case for the calibration matrix and in the end writing map-to-output was more efficient than explaning how to set the calibration matrix to every user that filed a bug report. If your touchscreen needs calibration *and* screen mapping, you need to manually calculate the matrix and then set it directly.
