Hi. Add this feature needed (especially por taxi drivers). When you have a route set from Point A to Point B, be able to add a point C, and D and Etc on the go, to go after point B (not before) without changing the route that already exists. And the application show you how much time and distance it will take you to go from A to C. Contact me for a better explanation if you don't understand. To keep things short. You should be able to add a new destination to go after the one that you already have and should be until 4 destinations more at least.
