RT Templates

I'd like to create a standard header or footer on RT tickets.

{$Transaction->CreatedAsString}: Request {$Ticket->id} was acted upon.
 Transaction: {$Transaction->Description}
       Queue: {$Ticket->QueueObj->Name}
     Subject: {$Transaction->Subject || $Ticket->Subject || "(No subject given)"}
       Owner: {$Ticket->OwnerObj->Name}
  Requestors: {$Ticket->RequestorAddresses}
      Status: {$Ticket->Status}
 Ticket <URL: {RT->Config->Get('WebURL')}Ticket/Display.html?id={$Ticket->id} >
