Image grouping by theme/timeline

Suggested by Stephen Sedman (Beta User Group)

One working method to prepare for album design is to make a series of folders of the separate themes in the wedding. Such as: getting ready, leaving the house, ready at the church, the ceremony, the end of the ceremony, outside portraits...

It would be great to have these "buckets" of photos populate the pages so that if a bucket of images numbered 10, then it would break it up onto 1, 2 or 3 spreads depending on your maximum number of images allowed, but not include any images from the next bucket.
