Adjustable length for 'Vibrate' action

Would it be possible to add a length option to the ‘Vibrate’ action? I’m using RD on an iPhone and I’d like to add some haptic feedback to my UI buttons. I’d need very short pulses for this – the current ‘Vibrate’ produces a longer pulse similar to push notifications when I turn off ringtones.

Sure, I will add adjustable duration for Vibrate action.
