I know that there is an option for the REQUESTER to get notified when a tech reply through email is appended to a request but what about the other way around?

I'd like that when a REQUESTER replies through email and THAT is appended to the request, the TECHNICIAN gets a notification about that reply.

Currently the conversation in the request gets updated, but the Tech has no idea that the Requester has responded to the email. makes tracking the conversation dependent on watching the ticket specifically.

We're in 10.21.

Thanks

David
