Side Mirror/Rear Window Defroster Question

Hey yall. This will be my first winter with my car and now that it's in dipping into the low 30s at night and in the morning this is becoming more relevant to me. I have an aftermarket remote starter that i use to heat up my car in the AM. As long as I leave the button for my heated seat depressed and the heat/front windshield defroster on when I turn off the car, then it will turn on the same way. However, I can't seem to figure out how to make sure my rear window and side mirror defrosters turn back on when I remote start. Any ideas?

Thanks!
