Great!
Yes, me too want to hear others users about it.
In our particular case, this request born from our way of structure for Client Reviews.
We create one ClientReview session per Image or Shot, then client can see only versions for each image in each session. It is more clear for us that one Client Review session with a lot of images and its versions, all them in the bottom area.
But this have the cons the huge list of Client Reviews, so a lot the emails to the clients.
So this would be my purpose to organise versions from multiple shots in one Client Review session.
