You got me there.
The pref board only appears on the breadboard view, and I don't think you can double load a board there - there would be a button on the bottom red bar, like in PCB view, to look at it from the other side -.
I suppose you could just put links on the top and remember to put them on the bottom.
Maybe you could use PCB view with the grid set at 0.100" and manually put in tracks top and bottom. Top tracks are yellow and bottom are orange.
