slots for the pokémon you gave for a quest and who appear in Jubilife?

[Alegria]

Hi, I was wondering if it would be possible to use PKHex to access the Pokémon which you gave for a quest, like the big Buizel or the three Pokémon that help on the crop. While the crop ones can be exchanged at will in the game, some others cannot be changed, and could have been shiny; I believe the game actually keeps all or at least part of the data in a similar way that it saves Pokémon in a daycare, I also believe some Pokémon games had NPCs trade Pokémon with you, then using your Pokémon in future battles (in BW2 regarding a trade in BW, and in Scarlet and Violet if I'm not mistaking) but I'm mostly curious about being able to change elements from Pokémon Legend Arceus's quests I've already turned in and can't change anymore, is that doable?

You'd have to compare a before & after save file to see where the PKM's data moved; ideally by noting the PID before giving it away, and seeing where it moved in the save file.

 

PKHeX provides the extra slots via the following logic:
