Change Ticket Subject by action

Feature request:

When I create a trigger there is for now only an option to change the subject of an e-mail what automatically goes out for example to:

Request received | {{ticket.title}}

In case of an auto confirmation e-mail, but I would also like to be able to change the ticket subject and put the ticket ID and or the product where it is about in it before the original subject {{ticket.title}} to see quickly witch product is this about scrolling through our ticket list.

Unfortunately i don't see any options by actions to do it and support advised me to put this request here.
