Allocating staff

Hi, 

Does anyone use bookings where it automatically allocates a member of staff to a meeting? 

We are trying this but require a pattern to it. Essentially we want it to go from staff A, Staff B then Staff C.

At the moment it is only going between A and B and it can be random. 

Is there anyway we can set it to go in a specific pattern without staff selecting the staff names?

If you require any further information, please do not hesitate to contact me.

Many thanks in advance
