Allow adjusting destination in Plan Route

When I select a destination station in Plan Route mode, I may sometimes want to change the destination to another. In another app I could simply select another destination and the new route is shown.. but I really miss this in ESG coz I have to tap Done, choose start station again then Plan Route, then new destination.. it's not very friendly...
I would also like an option to turn off the animation.
I would also like an option to enter Plan Route mode automatically when choosing the start station.
