[otrs] Queue Escalations - duplicate escalation email to supervisors

Greetings, OTRS 5.0.17 Our queue escalations are working as expected, with agents receiving escalation notifications via email. Is it possible to have a supervisor receive a duplicate of the above email? I'll be giving the Admin->GenericAgent facility a try (ie, calling an external script which sends the supervisor a similar notification email), but was wondering whether there is a more elegant way of achieving this. Thanks
