asp.net - Can you revert back to using Username in DNN 7.3.4 module permission grid? -

in dnn 7.3.4 when adding user individually module permissions grid can add them user's display name now. used done username. looks changed between dnn 7.0.2 , dnn 7.3.4. new way useless if have thousands of users , many of them have display names not unique. how identify john smith looking without username? please tell me there setting somewhere change username have not been able find one. if so, please tell me @ or missing.

personally never recommend provide user based permissions pages or modules. should roles.
