currently you can only set the time a desk is bookable either in weeks, days or same day. it would be very useful (especially for parking) to be able to set the time a space is available to be booked the day before at, for example 3pm. this would allow an admin to make any changes necessary to the group of spaces during the day up to 3pm (in this example). like close off spaces for contractors or last minute visitors. and still allow user to book those spaces within the working day (3pm-5.30pm). i have found a current work around (but only works if you are in one country), you set the group to same day bookings and adjust the time zone for that group to +9hrs, so the space is available to booked from 3pm the day before (your current time)
