At the moment, I couldn't create an automated message that goes out to guests between the hours of 10pm - 8 am.

The idea being that I'd like to have some "off hours" in my business..
So if a guest messages us during "off hours" then an automated message goes out to them and says something like "thank you for checking in with us. We are away from our desk right now. If you have any issues we will answer them promptly at 7am. If you are experiencing an emergency, please call _____"

I know that a few of your competitors offer something like this with their automated messaging
