This is the default sort order for all Task Groups on a Learning Plan Definition. When the Activity Sort Order is set to “Pre-added first, then in order added to the Learning Plan”, Activity Instances within that group are sorted first by the pre-added activity (or activities) as they are listed on the Task Group Definition of the Learning Plan, then by the order in which they are added to the Learning Plan with each newly new activity added to the bottom of the Task Group.

This selection is reserved for Admin who need a specific Activity Sort Order to cover their use case. A customization would need to be created in the backend to support this sort order option. The Administrator will need to reach out to their Implementation Analyst or to Support to use a custom sort.
If this option is selected without a customization implemented, then the sort order will default to “Pre-added first, then in order added to the Learning Plan” with one caveat. When this option is selected, any subsequent changes to the order of pre-added activities on a Task Group Definition will not be reflected on already existing Learning Plan Instances' Task Groups.
