Add the following to OrderGroup:
1. Add a field called orderGroupReason to OrderGroup , a Concept, to denote why the Group was “ordered”.
2. Will also add the fields previousOrderGroup, parentOrderGroup, and nestedOrderGroups in the sub tasks, linking to other OrderGroups, to maintain linkages between groups and support group nesting. We will be using group nesting to support the idea of Premedication, Chemotherapy, and Post Medication groups within a cycle.
3. Please refer to Talk thread here for more information: https://talk.openmrs.org/t/chemotherapy-ordering-data-design/19133/8
