Forwarded header via policy.

Hi Guys, Is there a way to set the 'Forwarded' header via a policy instead of using a long irule like in this document

I've currently got the XFF stuff set via policies like below

 

 

and I wondered if anyone knew a way to insert the newer 'Forwarded' headers in the same way?

 

Cheers
