Normally you can have multiple optimized routes that are scheduled for different dates. If you want to move route stops between the routes that are scheduled for different dates in the Route Timeline, you can bring them up on one screen.
If you want to bring up one of the selected multi stop routes in the Routes Timeline, click on the title of this route.
The corresponding arrows will point into different directions indicating that the selected routes are scheduled for different dates.
If you want to bring up the selected planned routes that are scheduled for different dates on one screen and move stops between them, check the Show All Routes in the 1 Day box at the bottom of the screen. This action will allow you to move stops between the selected routes that are scheduled for different dates without having to replan them, by deleting or inserting stops from multiple routes and re-optimizing them.
