Calendar - limit the books date period

It would be great to have an option to limit the period when you can book a specific appoint. This feature is currently standard in Calendly.

Example: We only want to take booking for Aug, but we want to allow the customer to book from June to until the last day of Aug. However, we can't do that in OP currently. Currently, on the last day of Aug, they will see booking dates for Sept and Oct as well - which we don't want them to be able to do.
