Enchanting Multitools

So I want to add stuff like paxels (which would be multitools in Mcreator) but they are unable to be enchantead with enchantments which can usually be applied to other tools. I know it isn't possible by default, but I saw something about it maybe being possible by editing the source code of the item. If this is a thing I would love to know, since I've been trying to make multitools enchantable for a while now.
