10 box naming problems

[Smoooth]

When I first started up 5 boxing and made my original 5 shamans I named them:
Schama
Schame
Schami
Schamo
Schamu
I leveled them up to 70 during wrath and when wrath came out I lost interest in them and leveled other classes. Now that I moved to 10 boxing I decided to have a 10 shaman team for pvp so I named my next 5:
Schamaa
Schamee
Schamii
Schamoo
Schamuu
I just got these 5 to 70 and got them ready to run together as one team for upcoming AV leveling. My problem is when I use

/target schama
/focus

They seem to ramdomly target Schama or Schamaa. Anyway to get it to work? Other than for focus I also need it for targeted heals.
My only idea has been to name change Schama to Schamá or something but that would only help the focus then I couldn't use a leaderless set up because all the others still wouldn't work. God damnit am I going to have to pay for 5 name changes??

try this instead:
/targetexact Schama

try this instead:
/targetexact Schama

If this works I will love you long time. I'll try it first thing tomorrow, thanks!
