Would it be possible to adjust the time interval for the start of a booking. If you now book from 9:00 AM to 5:00 PM, for example, the code will be active from 9:00 AM. I would like the code to be active from 08:45 (i.e. 15 minutes earlier). Maybe even an option to set this interval per user?

Unfortunately it is not possible to manually adjust the code via Nuki Web, I have already tested this. I also manually adjusted the time of the booking, also without success.
