I'm making a modpack where the progression is nothing like normal Minecraft and I would like to remove all existing advancements and replace them with my own. With the current mods in the pack I'm developing there are at least 100 advancements and removing them one by one by hand using a datapack is very repetitive and mildly annoying.

i say +1 i also im working on a modpack for some friends and i want to add some as well for some mods that dont have them at all
