Add option do remove markers from the maps after they are added to the route.
This would help when creating routes using big datasets (not allowing to add duplicates)
We will look into it, but will like more feedback from people on this.

When you add an object to a route, the marker remains "available" to add to route over and over. What I believe the requester is seeking is to grey out once an object has been added to the route. The only consideration I can think of regarding doing this would be to add a check box to make the route a loop. For instance, if you are traveling you may put a custom geolocation for your hotel, then route to accounts wanting to end up back at your hotel.
