Though we don't have anything quite like what you are talking about, there are a couple options you can use.
You can rearrange the roster by the Name, Country, or Squad, and that can help you locate people (granted this only works with people in the same arena as you).
Also, you can use the .goto playerID to go to the field of a friendly (I use this quite often to find out where someone in my squad is at).
Not quite what you want, but it's some other options to help.
