Customer conversations with TO / CC fields

Currently when a technician replies / forwards a conversation they have the To and CC fields to send notifications / alerts so people are aware that a new notification is added to the ticket, but when a customer adds a conversation they don't have these fields so they can't "alert" anyone that a new conversation is being added.

Our client asked us about this feature since they need certain replies on tickets belonging to their development group to be notified to a certain group of people (or maybe an option to automatically notifiy the mails on the "Id(s) to notify" field when adding a conversation could work, or the ablity of making business rules on adding conversations to a request, as a workaround).

Currently there's no possibilty to notify anyone when a requester adds a conversation (except for the red new conversation icon on the request search tab).

Thanks and regards.
