Of course there are. I forget what there are called, but there are setback seatposts where the setback is measured in inches vs. millimeters. I wonder though if the o.p. really, really needs one. Most men's legs are accomodated well by the standard 25.4 setback on 'normal' seatposts along with the setback allowed for by 'normal' saddle rails.
