Is it possible to add an entries field to recurring events that can be changed per occurrence? An event in Solspace Calendar that repeats weekly should have an entries field, that can be changed per single occurrence. E.g. Tuesday’s evening class is usually tought by teacher A, except next week, where it’s going to be teacher B (both teachers have an entry I’d like to link to in the event’s popover).

Is this possible?
Calendar's event recurrences are only simulated/inflated by a repeat rule for the main event. Since there is no database entry for each recurrence, there's unfortunately no way to achieve something like this at this time.
