events dependency on other events

I was wondering if there’s a feature to have one event dependant on another.
Here’s an example.

Joe has an event from 10:00-11:00, and another from 11:00-12:00 and another from 13:00-14:00

If the event from 10:00-11:00 is moved say 30 minutes forward can the other 2 events automatically move 30 minutes forward?

however- if the 11:00-12:00 event is moved, only the 13:00-14:00 event should move, but not the 10:00-11:00 event (as it’s already passed)

I just found this software today, and having a hell of a good time with it.


scheduler doesn’t have this feature out-of-the-box, but it can be managed using “collision” extension. It allows to control the number of the event in the time-slot and detect “crossing” events. Than you need to set correct start/end date for each occurrence.

Thanks Serge.
Not exactly what I need, and won’t work for me.
I’ll most likely develop a trigger on the database to do these changes (will need to add fields to database of dependency.)
