Holiday/Night Button

Why is a holiday/night "button" not available in the RingCentral universe? This has been a feature of traditional PBXs for DECADES. There needs to be a way that Holiday/Office Closed greeting and menus are simply activated, and a selection of several menus should be available. Not all businesses have regular hours, and circumstances sometimes dictate that the office is closed. Snowstorm? Fire across the street? My client's 20+ year old Toshiba PBX had a simple way to do this. Last person out would activate it OR it could be activated remotely through the voice menus.
