Feature to change the Parent of the Subtask

[sivadevwiz]

Many a times we create subtasks for a parent task. Then we realise a new parent task is required and then create a new parent task and want to move some of the subtasks already created to be moved into the newly created one but not able to move.
Also there's no option to change the parent of the subtasks.

This feature would be very essential.

You can do this via drag and drop, if both parent tasks have sub tasks. But I agree that this could be improved.
