Wheelhouse does not handle calendar blocking at this time. You will have to unblock your calendar on your specific channel, whether it be Airbnb, TripAdvisor, or our Property Management System partners.
If you want to help us progress toward adding the feature request you've suggested, you can go to our feature request page at https://wheelhouse.canny.io, register, and create a post with the feature request you suggested. https://wheelhouse.canny.io/feature-request/p/block-off-calendar-sections
We are working on adding this functionality in the future.
