Is there any way to check pokemon location (funny kanto love island quest) other than manually check in the pokecenter?

Because love island required certain amount of kanto pokemon

 

The problem is after kanto i directly went to johto, so it is inefficient for player to check every single pokemon in pokecenter for their caught location

Dear @Illjyf17

 

Requirement of unlocking Love island is caught dex 120 Kanto Pokemons and 38 evo dex any regions.

 

You can check caught dex by; 
1. Open you Pokedex and manually count
     + Pokemons you already caught = small Pokeball icon below
     + Pokemons you evolved by yourselves = small star icon below
2. Talk to professor Oak in Pallet town

 

You can check Pokemons' spawn by; 
1. Open you Pokedex and click on Pokemons
2. Use command '^s PokemonName' on Discord bot channel
