Hiding screens which comes after enroute, start activity, end activity

Summary:

Hi Team,

We have requirement from our client that when they click on En-Route, Start and End Activity, they don't want to see additional screen which comes wher they get option to change time, etc.

1. After clicking en-route, we get screen which shows map, activity details, option to select travel time. Customer does not want this screen. After clicking en-route they expect status to directly change to en-route, without selecting any travel time. Is it possible to hide en-route screen which comes after clicking en-route button.
2. Similarly user gets option to enter start and end time when they click on start and end activity respectively. Is it possible to hide those screens and status of activity should change to started and complete directly without entering time.
