No. I'm sorry, but unless any of the bookies actually have special bet types like that, then I'm afraid you can't. As it is, the bookies won't usually permit multis where one of the legs affects the outcome of another leg, so I'm sorry, but you can't do that.

With the AFL, Centrebet has that option where you can pick the first goalkicker and either team under or over 24.5 points. If one of the bookies has an option something like that on the NRL, then you can certainly use it, but otherwise, your free bet must be just a single bet.
