Non-assigned stops are all those stops that are not associated with any plan.
What is the Unassigned Stops Page?
The page of unassigned stops is the space in which the set of unassigned stops that you have in the same project are shown.
Thanks to this page of unassigned stops you will be able to easily see the total number of unassigned stops that you have, either because they are canceled or incomplete, and thus be able to assign them again to another schedule with the option to move stop.
Move an unassigned stop
To move one to not assigned, you just have to select the specific stop using the checkbox and the Actions box will appear above.
Now, click on Actions and then on "Move to Plan".
Select the plan you want to change the stop to and click Move stops.
