Draw Enemy Names Through Walls like in Spectator

[php]

Like Ni3ls said you could do that with HUDs/waypoints but I think there was a cvar for it also but i'm not sure.

I was hoping for a cvar or maybe a built-in function but couldn't find any in the script documentation for 1.7a/libcod/cod4 stock..
I know I could do the hud elem above a players head but I was hoping for something cleaner such as the spectator's draw enemy names through walls.
