A Selle Italia Flite is a very "forward" saddle - the rails are short and the sweetspot of it is pretty far forward.
If you're comfortable on the saddle, you could get a seatpost with more setback. If you're looking at Fizik saddles - the Arione is a long saddle with lots of fore/aft adjustment: both longer rails than the Flite, and a much larger zone of adjustment w/r/t sitting on the saddle itself.
