If you are looking for changing the text (name) that you want to see on the hunt group member, you can do the following.
You can create a CTI RP with the Hunt pilots DN and give a Dummy DN for the Hunt Pilot. The CTI RP should CFwdAll to the hunt pilot. You can set a Display name for the CTI RP and that name will show up on the phones that belong to the hunt group. THe text will be "Forwarded For ".
This should also change the display text on the calling phone.
