Point of interest with alarm: Point of alarm?

I would like to see the possibility of having an alarm go off when a point of "interest" is reached. Example: I ride my MTB in the back country. I do not want turn by turn navigation but only to hear an alarm when a specific point on the map is reached abnd that I previously added . Could be a crossing, a fork in the road etc. That way I would not have to check my phone every time I reach a crossing in order to see if it's the one where I need to turn. Could be called "point of Alarm (POA).
