ON-PREM: Notification to internal users via email about server maintenance

We are an MSP and allow our clients to use ScreenConnect as a way to access their machines. We routinely perform ScreenConnect upgrades, which disrupts our users ability to access their PCs. I'd love it if there was a way to hit a button in the Internal User store to send all users in the internal users an email. I'd use it mostly for maintenance window announcements, but it could be used to notify of upcoming 2FA implementation, forced password changes, etc.
