Can I select different means of transportation for each appointment/frequent?
Yes you can, means of transportation are not bound to a specific appointment or frequent. You can select a different way of transportation by navigating to the dashboard.
Click on the change icon at the top right of your appointment.
Now you can change the mode of transportation by clicking on "Travel By".
Now you will see several transportation icons (by car, by train and by bike). Select your means of transportation to see the time at which you need to leave.
It is currently not possible to assign a mean of transportation to a single appointment or a frequent. You need to select your way of transportation for every single appointment.
