Can we have a staff getting booked by multiple users at the same time slot.

Scenario:

Staff A is capable to assist or serve multiple users at the same time.

So, customer A can book a time slot 4.15pm with Staff A

and I need the capability of customer B being able to book the same time slot of 4.15pm with Staff A.

Diving into the codes I found an option in the file bookly-responsive-appointment-booking-tool/lib/slots/Booking.php

/**
* Get one_booking_pre_slot.
*
* @return int
*/
public function oneBookingPerSlot()
{
return $this->one_booking_per_slot;
}

I tried setting this to false so to allow multiple booking per slot. But it didn’t really work.

Any suggestions?
