Flexi Task is assigned to group (Create individual tasks for all group members is not checked), first response applies, reject or approve outcomes.
After the task has been approved or rejected, a people picker/group field on the item is updated with "Last Task Respondent."
When the task is approved, the field is updated with the person who approved the task (this is correct).
However, when the task is rejected, the field is updated with the group (not the person who rejected the task). How can I get the person when the task is rejected? I don't want to check the individual tasks for all group members option. I want it to work as it does when the task is approved.
