So is there no way to do this without replacing the entire system I already have? I didn't really want to buy another transmitter and receiver or relay board. I already have all those. I just wanted something that would feed the transmitter I have in the manner I explained. Can that be done...

The problem:
I have purchased a simple 12 channel remote relay system for about $20.00...
