Huhm. Correct me if I'm wrong but I don't think that's necessarily possible. You probably mean you'd give the markers name depending on the player's name? Well, as you can see in all multiplayer games using the same system they use "Alpha", "Bravo", "Charlie" etc codenames for everyone...
Why not colourcode them or something instead.
But if it's possible, do tell...
Wolfrug out.
