no

Describe the solution you'd like

currently we are defining in the configuration to notify the reviewers about unverified reports of the last month.
and the reviewers are receiving three reminders, and in the last time, the defined email in the configuration is receiving the email as CC.

what we want to do is:
to make the first reminder only to the reviewer,
and in the second reminder, we should involve the supervisor of the reviewer as a CC in the reminder email.
and in the third reminder, the email that is defined in the configuration should be in the CC next to reviewer supervisor
