Ability to mass assign performance feedback

Summary:

Manager needs to collect feedback on their managers they supervise, they need to collect it during the performance review process however, the manager would have to select every employee one at a time (this is not a good process for senior leaders). Is it possible to mass select the managers team and then submit all at one time so the the feedback form is sent to all team members at once?

See below screen shots of steps:

This panel opens next where manager can select the team of the manager being evaluated.

Need a way to select more than one team member at a time. Senior leaders may have many managers who then have many employees.
