Linked pokédex entries across same game dexes and game saves

Currently, within a Pokémon game, the Pokédex is split into multiple separate dexes.

Pokémon which share entries across multiple dexes have to be individually ticked off multiple times this way. I think an elegant solution would be to give users an option to have such entries be linked across Pokédexes and game saves. Moreover, I’d love to see an option to display all three Pokédexes in one fluid layout as well as an option to “show all.” Currently, I spam press the “Show more” button several times. 😅

This could be done with the game saves as well. Same thing, but bigger. Ticking off a Pokémon in Scarlet and Violet could seamlessly carry over into having it ticked off in another selected game save. One could select all the game saves they want to link to each other.
