Message template is it possible to have an automatic email to candidate after an agent referral

Content

Hello,

For the message templates , we would like that once the agent refers a candidate the candidate will automatically recieve and 
email just like there is for a referrer that an agent has referred the candidate.
I looked at the automatic triggers, when choosing 'All canidates' in the message context and i cant see a trigger like ;
-'Job-Specific Referral, Agent' . 
is this option possible ?

see screen attached 
Thanks,
