Global Message to alert all clients on system issue or maintenance.

Any updates on this issue?

There really is a valid need - from a service desk admin perspective - to push out notifications about system downtime / maintenance through the application - to all customers.

The workaround is not sufficient. 
Customers may not be logged in the support portal all the time / or frequent enough to see the 'message'.

What we need is are two options -  to notify all customers or selected customers when a message gets posted or notify the customers about the actual message.

Thanks!
