Is there a proxy function which allows line managers to delegate completion of performance docs?

Summary:

When managers are unable to complete performance documents, they currently have to transfer them to another manager to complete on their behalf. Is there any form of proxy function, to enable the line manager to delegate the task to another employee, without having to transfer the whole document?

We do not want HR specialists to act as the proxy.
