Adding custom biome to vanilla Overworld generation.

Is there any easy way to do this? The closest I have gotten is by creating a datapack with a path to data/minecraft/worldgen/world_preset/normal.json, (to override normal behavior of the normal world preset), copying+pasting the exact normal.json file contents from the actual game files, and replacing the preset tag under "minecraft:overworld" with a "biomes" tag. Problem is that if I want to use this approach, I would have to add in every single biome with presets to emulate vanilla generation, which wouldn't be an issue if there was a file that I could just copy which contained all of that info. However, I cannot find such a file in the game files, since the vanilla normal.json in world_preset uses a hardcoded preset as opposed to listing the biomes out in the file. Is there anywhere that I can find json file that contains all of the vanilla biome info for the normal world preset? Is there an easier solution that I am over looking? (apart from just creating another dimension, I specifically want a biome that generates amongst vanilla overworld generation) Thanks for any help 🙂 (Attached file contains my datapack's data/minecraft/worldgen/world_preset/normal.json that succussfully makes cherry biomes the only surface biome to spawn in the overworld. )
