Ability to view Pokemon'(s) Sprite when editing Pallete

[an8bitbatty]

Hello, I'm currently trying to edit the Sprite Palettes of the Pokémon, and I've only recruited so many to be able to view them after editing the Palette, and then having to view them in-game, it would make it immensely easier to edit them, especially the Pokémon that I currently don't have recruited, if I could see a Preview of the Pokémon's Sprite. If the resources exist to be able to view these Sprites when altering the Palette, It'd be most appreciated if you could implement them into the editor, Thankyou! <3
