Adding "Assigned by user" in Ticket template

In my ticket notification template for "Ticket assigned", I have the following:
Ticket ###ticket.id## created on ##ticket.creationdate## has been assigned to ##ticket.assigntousers##.
And this works just fine. But it only shows who is assigned to solve particular ticket.

Would it be possible to add a tag like "Ticket assigned by user"?
This is to show all other technicians in email notification who assigned this particular ticket to them.

I know you can check Ticket's history and see there who assigned it, but this would be directly in email notification.
