How would I predetermine stats for a Pokémon?

[--Nirvana--]

What i would like to do is predetermine the ability, nature and moveset of a Pokémon I have yet to pick up (e.g. You would pick up Eevee in Fire Red (though it's stats are random)). Is this possible? If so, how?

Thanks.

Of course it's possible. The wiki says so.
