In Hierarchical groups, data flows from top to bottom. From groups to subgroups.
- Touch the + beside the particular group you’d like to add a subgroup to.
- Press New group.
- Label the subgroup and select the arrow.
- Choose the members you wish to add.
- Pick the group and then touch the arrow for a preview.
- If everything appears as intended, press the checkmark. The new group now becomes a subgroup under the group.
