Calendar blocking time in hours

Unpaid reservations block availability in the calendar.
In the settings, you can adjust the blocking time, but this is measured in “Days”. This means that the minimum blocking time is 1 day.
I’d like to reduce this time to 1 hour, as 1 day is far too long!
How can we do that ?

Sorry, there’s no such option yet but we’ll consider adding more precision. A possible workaround is removing this status from Blocked Statuses, then the first customer to pay will block the dates.
