Batch Change Dates in Aperture

I want to batch change hundreds of images in 1 event (or project) in Aperture 3 to be timed apart by the time designation I set forth on the batch process. I have easily done this in iPhoto 8 by selecting all the photos, ctrl-clicking "batch change" and changing the date to be set for a given time, and adding 1 minute to each photo.

I'm building a book by interleaving 2 events of scanned images by their times. It works great in iPhoto, but I can't process the images like I can in Aperture.

If anyone knows how to batch change dates as in the above procedure, let me know. Thanks.
