No I like to find out how long it will take to go to one place and then another. With driving selected you can add arbitrary waypoints. For public transit you can have one destination only. I suppose it makes sense because they like to tell you via schedule how long it will take, and the map would need to know how long you will stay each location. But when I’m looking I’m just checking if a route exists, not which time I will take the train.

Ok so a basic version of adding a second stop, on a route using public transit.
