Yup, exactly what I hoped to avoid. Maybe a new feature to consider for future release.

I wonder how fast it is, because almost every time I use the -A flag, the iterations over 100k users takes a long time. We email the 'bulletin' to all of our users, everyone gets a copy, that way an admin doesn't need to do it, but it does mean that we duplicate the data quite a lot.
