Automate the process where managers collect participants feedbacks in the PD

In the Manage Participant Feedback, the manager will select manually the people who need to get feedback for the employee performance evaluation. Instead of manually adding the participants we want to automatically select the employee's all subordinates. Is there a possible way to do this process?
