Reprogram Driver 1 remote to Driver 2?

I just purchased a used 2004 TL, and it came with two Driver 1 remotes. I suspect the previous owner had lost one, and the dealership ordered him a new one, but not the correct one. Is it possible to reprogram one of the Driver 1 remotes to be a Driver 2 remote, to take advantage of the seat/mirror settings?

Thanks!
