For Version 0.7.0 (The next one) I finished implementing this.
It will jump you to a day 60 position with most beginner and intermediate stuff already done, discounts maxed, etc. and you can tackle the Sun/Moon Stuff from their delayed starting positions. You will be able to select this head start option by simply clicking (tapping for phone/tablet) the image of Bibi 20 times before you start the game proper:
The game will inform the player they can do this after reaching a certain point. Again, not in yet, but soon(tm), I hope it will help.
