Email & Text Out of Office Notifications

My idea would be to be able to send automatic replies to customers when I am out of office. When going on vacation, there isn't anyone to check my texts and emails through Dealermine. These messages will be left unread until I return. A lot of my customers schedule their appointments this way. It would be great if they would get a message when I am out of office so that they can contact us by another means to schedule their appointment.
