These changes will come out quite soon and will therefore be put under an experimental flag in the beginning for customers who want this change immediately.
After the change of allowing multiple activities connected to a group with different Syllabus it was noticed that the naming of the activity was wrong since all activities was named after group name, the activities names should be fetched from the Syllabus. This is now being fixed.
We previously did not have a need for parent activity, but after the change of allowing multiple activities it is sometimes needed to have a connection that is concluding all different syllabuses for schedule purposes. So this change also sets a parent activity that will keep the group name and which child activities point towards.
