When going to destination, Waze can help identifying a parking in proximity, and navigate me there instead of the precise location. This is helpful, and sometimes can be very helpful if the maze of one-directional streets or blocked roads make parking 200m from the location much more accessible than the original address.

But for "extra stop", there is no such assistance currently. This is unfortunate: when sharing the car, I want to drop my wife near her office and continue to mine, but she can walk some 500m if it saves time. In downtown, the time gain may be quite significant: to stop 200m South from her office may one day be 20 min faster than choosing the route that passes 200m North. The next day, traffic conditions may revert.
