Sending gps commands through xbee

I am currently working with a setup like this:
gps adafruit receiver -> xbee 1 [100 ft] xbee 2 -> arduino

I have managed to figure out how to send the necessary gps data from the receiver to my arduino and print it. I am wondering if there is any way to send gps commands back into the gps receiver (through rx) using serial pass through. I would need to send a message to the receiver like “$PGCMD,33,0*6D” to change the settings on the gps itself… this should be possible but im not entirely sure how to do it. Any suggestions would be appreciated.
