Mobile: Batch Move

I really like how in the iPhone version of Nirvana, you can tap to delete multiple tasks at a time. However, there is not a similar way to do this for moving tasks. Currently, you tap done if you want to go back, and you tap on a task to move that one task.

Here's my idea. The "Done" button should only leave move mode if you decided you don't want to move a task after all. If you do tap a task, it is selected in blue or something, making it obvious you just added that task to the tasks to be moved. Then, the done button would actually pull up the "move to what location?" menu. I think this would make moving multiple tasks in the mobile app simple and handy. :)
