I am planning to travel through Europe this summer. I read that the mobile app does not get updated/synchronized as often so I resorted to using only the website instead.

Now, while planning I am trying to find a way to add all my different trips to a list or something comparable on the website. Is there a way to do this, and if so, how do I do this?

It will help me a lot with keeping track of all the reservations and bookings I need to do in order to travel comfortably and orderly.
