Red Alert 3 Pre Steam Install on Steam

Hi, I bought a copy of Red Alert 3 back when it first came out, it is the Premier Edition of the game. I tried to get the game to activate on my Steam Account, since RA3 is available on Steam. Is it possible to get the game to show on Steam, with out me having to buy a new copy of the game? Any help on this matter is greatly appreciated, thank you.
