Ability to add a calendar event that isn't bookable

As a merchant, sometimes I want to put a notice on the calendar that isn't bookable, may not even have a time, but applies to a day or series of days. For example, "No pokemon today" or "XYZ unavailable" over a span of days. This feature would be helpful for merchants who rely heavily on Experience's calendar feature. https://help.experiencesapp.com/en/articles/4770454-add-a-monthly-calendar-view-to-your-shop-to-show-all-your-experiences-in-one-place
