Keep tracks of shiny pokemons?

[Asia81]

Would it be technically possible for PKHeX to "scan" or keep a tracks in some ways for the shiny pokemons currently available in the overworld?
I.E. having a list with pokemon currently saved on the map and their location.

PKHeX already provides a list of stashed Shinies in the "Other" tab.

If you want more detailed information, like coordinates, use this plugin (no support provided for it on this forum): https://github.com/santacrab2/ShinyStashMap
