Apply a change to all available months

Module does what it's intended however the configuration is a pain. first of all, when you create a room and set availability by default, when you go to the booking page, no dates are available by default so you need to open the availability menu and submit changes month by month, it really takes a lot of time. so I wonder if you can fix the issue that when you create a room and set an availability by default, it becomes available automatically in the booking page. Also it'll be very helpful if you add a feature so you can add one change to all available months instead of submitting changes month by month. To be honest, without these changes, this module can not be used beyond a bed and breakfast or small motel, not practical for real hotels with lots of rooms.
