Multiplayer CALLSIGN Tag Needed

[WyattB1]

Hi I would like to say I use Plan-G extensively next to the FSX radar scope when controlling. It allows me to zoom all the way in on people on the ground so I can give them ground clearances. I LOVE that I can use it for that but I haven't found a way to turn on Callsign tags next to the other players aircraft. If that was included this program would suit every ATC need. Please tell me if there is a hidden approach to turning those on as I have not found it in the settings. Thank you very much!
