Once you have planned a route, you can easily reverse the waypoints of the original route to create a new route. The new route will appear in the Enroute Charts View, RoutePack List and Nav Log.
To keep the original route intact and add a new reversed route:
Copy the original route and paste into a new RoutePack.
Select either of the routes (old or new) and click Tools > Reverse Route.
To reverse a route:
Select your route or route leg in the RoutePack List or the Enroute Charts View.
Click Tools > Reverse Route.
