[Audio✓] ? Pokemon cry editing

Hi, how would I edit the cries of the ? Pokemon in the Gen 3 ROMs (More specifically fire red).
From what I've heard, whenever you edit one of the cries it messes the others in the ? category up, at least that's what I think I heard.
How can I edit these cries without messing up the rest of them in that category?

All of the ? (I call them limbo slots) cries are linked to the Unown cry. So whether you change the Unown cry or one of the limbo slots cries, it will also change the rest. But there is the way to unlink them from one another: https://www.pokecommunity.com/posts/9598162

Edit: It seems I can't Import cries for the limbo slots, and I think I would have to repoint the cry table to do so.
