The role configured by the mail automaton has no personnel, so how not to send it to administrator

I am using Windchill PDMLink Release 11.0 and Datecode with CPS M030-CPS16

Workflow template The email automaton is configured with multiple roles. If one of the roles is empty, the email will be sent to the administrator. Can it be configured not to send the email to the administrator.
