    You can make use of our Appointment slot widget, that way, you can set how many slots are available, and when selected, the number of available slots will decrease after submit.

    You can find the widget here:



    Thank you.

    You can achieve that using the same widget, you can add a slot for that time and date, and set the available number to 2, this way you will have 2 slots available for the same time and date. 

    Thank you.
