I hate those 1-bolt seatposts. I don't know if there is a good solution, but here's something that's worth a try: It's my understanding that the seatpost is reversible. Maybe put it in the forward position then jam your saddle all the way back in the rails, this will decrease the leverage the saddle has which is making it tilt. Hopefully, you can achieve the same setback.
