How Do I Move Multiple Tasks Into A Summary Task?

There are couple ways to move multiple tasks into a summary task.

1. One way is just to simply drag and drop each task one at time to the desired Summary Task.
2. Another way is to add each task to your clipboard (make sure clipboard is empty before starting)and then clicking on the summary task you wish to move the tasks to, which bring you to the task detail page of the summary tasks and from here you can select to move the items from your clipboard to the summary task. Below is a video link demonstrating exactly how to do this.
