Switch departure and arrival locations

I think it would be nice to add a button to interconvert the departure and arrival locations. This is useful when I am searching for a round trip. After looking up prices for the outbound trip I would select Anfrage ändern to get back to the search form. There I would just click the not-yet-existing switch button.

Here is an screenshot from bahn.de indicating the switch button:
