In this video you can see how set your favorite position with two hex keys of 3mm.

You can choose between CENTRAL or BACK if you plane position is respectively zero offset or back offset, and between LONG and SHORT if you prefer respectively a lot or a small distance between the forward and back position. So you have 4 settings:

SHORT CENTRAL: zero offset middle position, forward and backwards positions are quite close (road, gravel, xc)

SHORT BACK: as before but with middle position with back offset

LONG CENTRAL: zero offset middle position, forward and backwards positions are extreme (downcountry, trail, enduro)

LONG BACK: as before but with middle position with back offset

After choosing your best set up, you can fix the seatpost in the middle position and regulate your saddle for plane riding. You can modify the set up whenever you need.
