Can the Fortigate insert XFF header when it is running version 6.0.9

Hi;

In a pervious post I came to know that Fortigate with OS version 6.2 is capable of inserting an XFF header. My question here is whether version 6.0.9 can do that. My client's FortiGates are running version 6.0.9.

If yes, does it use the same techniques used in version 6.2 to achieve the XFF insertion?

Kindly
