The LM programmer software should let you do this.

Remove the XD-16 which you want to reprogram from the MTS serial chain. Insert the terminator plug in the serial IN of the XD-16 and the cable that goes to the computer to the serial OUT. Launch LM Programmer. Once in LM Programmer go to the "Input" tab. The LM Programmer will read the MTS record. You will now be able to select the channel that you want the XD-16 to display.

You should be able to select AFR or lambda to display.
