Ride against your friends even when they aren't online?

Is there a way to ride against your friends when they aren’t online?

For example, my brother and I live 3 time zones away from each other, but are both selecting the same workouts. Is there a way I could see his effort on a particular workout show up as a ghost rider of sorts?

It would seem as though all the data is in Zwift to make this happen, and would be really helpful because life simply gets in the way, and there are very few times he and I will be able to coordinate a workout at the same time of day.

Not at present, but there’s a feature request that would support that.
