Subject Modifier for forwarding

Is there a way to permanently change the forward modifier from “fw” to “fwd”? My online CRM supports forwarding emails and letting it parse the system, but it needs the subject change to be “fwd” instead of “fw”. I found in the settings where you can change a little of the modifiers but not actually the two letters from fw to fwd.


Unfortunately this is possible to be done only manually, in 6th version there will be possibility to change between Fw[3]: or Fw: Fw: Fw: or just Fw:
