I can't find such an option either, and yes I agree that it would be very useful. I personally set the view to "horizontal scrolling" and "odd spreads" for every single pdf I open. One good thing is that if you change the view for a given pdf file, it remembers the next time it is open. Still, it would be nice not to have to set this for each newly open pdf file.
