Customize envelope sharing

It would be very useful to be able to limit envelope sharing to only those envelopes sent by the DocuSign user and not to share envelopes on which the user has acted as a signatory. In companies where the Human Resources department has the DocuSign tool and sends personal documents to employees, it is not possible to share DocuSign accounts between users because this means giving other users access to these personal documents that have been signed by the user as an employee.
