How do I change unit status to hero?

How would I go about changing an ordinary unit's status to hero? I know that "Gladiators" has this set because i looked at the a condition that asked if the unit was a hero. I just dont know how to change a unit to a hero status. I need this to be able to revive units. thx.

You use the Unit editor in the world editor. You get the world editor with the game and the unit editor is the helmet in the top navagation bar.

I'm using the unit editor that came with warcraft. i just need to know how to quickly turn a unit into a hero and keep it's original stats without having to go through every single stat and match it with the original unit. know what i'm saying?

Yes, but what you are asking for is impossible.

Thank you very much Conquistador. I would have been looking for a way to do it forever. that's all i needed to hear. thx
