I really like the plug in a lot and it does pretty much

I really like the plug in a lot and it does pretty much everything I need it to do. I would like to know if I can block off a period of days or weeks to prevent bookings? We are thinking of closing for renovations and would still like the possibility of clients to able book on line around those times. What I'm really saying is instead of adding each date we are closed in the "Exceptions" I could do a "from - to" instead?
