When you pick the airport of departure and the destination, scroll down for this option. As far as I know, when booking an award flight for someone else, you do not need to make any "nominees" list beforehand in M&M. I made such a booking on the phone and I just gave them the details of the passenger, incl. their birthday and passport no. if I remember correctly.
