I've just read https://moodle.org/mod/forum/discuss.php?d=213926 - I'm not quite sure if it's the same question as I have, or a slightly different one.
I've experimented with the scheduler to let students select time slots for vivas. In order to share out the students, they're randomly assigned to a different tutor.
The only way I could see for it to work was to create a group (all students assigned to tutor A), then to create a grouping (Grouping A = Group A); set up the scheduler - for tutor A (so just visible to Grouping A); set time slots & select Tutor A as the tutor. Then do the other groups.
Clearly, as they're vivas it's only 1 student per slot. So, I want them to select their own time, but let the rest of the group (who haven't really got anything to do with them, other than randomly getting the same tutor!) choose their own.
If you set
Site Administration -> Plugins -> Activity Modules -> Scheduler -> Enable group scheduling to 'No', as suggested, can you still attach groups to scheduler?
Or, can anyone suggest an alternative solution?
(The appointments were set for one person, but it seems that if someone clicks the 'group' you end up with two in the slot regardless.)
