KOM, Sprint opt in option

Is it possible to implement a feature which allows Zwifters opt in to receive an invitation to sprint or go for a course record or KOM record. The point is when Zwifting in Watopia, London, Paris or New York etc, it’s not often I wish to participate in the event but still end up getting listed after crossing the line as having participated. Firstly, the timers appearing on days I’m uninterested or don’t feel like it are a distraction and ruin my Zwifting experience and secondly and perhaps more importantly, the rankings are not very correct or representative.
