Selle Italia Novus Flow S2 angle adjustment

[3Pio]

Hi there.. I just got Selle Italia Novus Flow S2 saddle (also have L2 for test, but seem too wide).. Any tips how to adjust angle of the saddle? Im using Selle Italia SLR Carbonio Flow, and there is easy to adjust (just put it horizontal).. On Romin Evo Pro i also have, i put horizontal 2/3 of the saddle.. How to do it on Novus?
