Shutdown & Re-Boot -Long wait timesin use plus a way to do it now needed

We are an education environment and we need to give the user the shutdown in 6 to 8 hours with the abort the can cancel it if they need to. But, they don’t have the option of hurrying it a long by clicking on a button that would do it now. could really use this feature
We have to do this to avoid interrupting the class room instruction

Thanks for the feedback, we will look at adding it to a future release.
