Time automatically assigned

Hello,
I would like to know if the plugin gives the possibility to automatically assign the time of appointment, based on a chronological order within a pre-set time period per day. In this way, within the same day, User 1 would be allowed to book only at 9:00, while User 2, later, would be allowed to book only the next time slot, let’s say at 10:00 and not, for example at 12:00.
This would avoid the issue of having unbooked time slots between booked ones.
Is that possible with this plugin?
Many thanks!
