allow group booking for a single consultation

allow group booking for a single consultation

Hi, 
I have a scenario where we meet clients throughout a day in a capacity of up to 4 people.
Our session is taking 30 minutes, so through a working day of 8 hours we will have 16 sessions (each can can accommodate up to 4 people).

To implement this scenario I wanted using Consultation type of Group Booking - the problem is that I have to create a separate consultation for each time slot in a single day (group booking requires to provide exact time in a day for the consultation) - so in my case 16 consultations for the same session. It makes it very difficult to manage and impossible to scale. plus the experience for users is bad, as they would have manually select consultations. 
for example calendly handles it very easy with a single group event.

Did anyone face a similar issue? How do you handle it in Zoho Bookings?
Thanks!
