In one of our flows we have a hotline that our stores use when they need to reach our contact center in an urgent matter. 3 out of 4 selections are available between 8 AM and 9 PM whereas one is only available between 8 AM and 4 PM.
In our current setup we've solved it with a task (see image). But an easier setup would be to have a button that enabled us to override the default schedule and set specific opening hours for that particular queue as well as selecting a user prompt to play outside these specific hours. This function could also have a set time zone based on the default language of the flow itself, thus following summer/winter time automatically.
