Domino Auto Update capability to execute actions/programs during deployment

When a (planned) deployment of the Domino Server update via Domino Auto Update requires the server to be restarted, it would be useful to be able to configure one or more tasks before and afterward.
For a manual deployment, for example, we often broadcast to users, once 10 minutes before the server shuts down, and again 5 minutes before.
This is followed by a message to the administrators confirming the action has been performed, and sometimes an additional task such as starting an agent.
This could be easily incorporated as options in Domino Auto Update, for example, dropdown/list boxes for pre- and post-deployment with a time in minutes before and after in the Schedule Deployment form. The list box could display the available Server program documents for selection.
There could also be an option to email the deployment results to an email address or group.
