Does anyone know how to Enable the Windows Update restart now/restart later dialog?

I have a software update that needs to be installed, however we do not want a forced reboot, but need the user to reboot relatively quickly. The easiest way to get them to reboot is the windows update reboot dialog which is a "NAG" dialog that will continue to popup until the user reboots the machine.

Can anyone discover how to do that in Setup Builder?

Thanks for the help.
