It does not have either of these features. For shot control you have water temperature control via the digital PID. I would say the way the pressure hots the group head from the vibratory pump is "soft" - it ramps up to a tad over 9 bar in the first seconds. So in a sense this preinfuses: It doesn't hit the coffee at 9 bars straight off! But no, no true user-controlled pre-infusion
