Agile: Add option to move task to the backlog once that task is pulled into an iteration

If a task is pulled into an iteration, we would like to be able to move it back to the backlog...currently you can only Add to Iteration or Add to Kanban Board.  Would like an option to Add to Backlog.  There are times when tasks are not finished at the end of a sprint and we do not want to move them to the next sprint - we want to move them back to the Backlog.   Currently, we must do a manual process: first we remove the pod name from the assignment and then manually add the pod name back to the assignment.  That is the only way to get the task to the backlog.  This is a waste of time.
