How to change Hero name and proper name?

[Doom-Slayer]

Iv been wondering for a while, as iv pretty much run out of things to do with the basic trigger menu,(ie drop and choose), and I was wondering, is it possible to modify a hero proper name and normal name? Iv seen conditions for them, but no way of changing them, if anyones got any idea that1d be awesome thanks. Btw Id prefer it to be the basic trigger thing(GUI or w/e its called) but if you cant JASS would be fine. Thanks

No, you cannot change them in-game. You can, however, create a similar unit in the Object Editor and replace them in-game.
