Using procedures in a crafting recipe?

I would like to create a smithing recipe in which NBT data of a written book in slot 2 is copied over to the resulting. item (a tool). This would be used to add the text inside the book as item lore. Is there a way to use a procedure for this? I've made one which does exactly what i described, but i don't think there's an obvious way to apply this when crafting the item, seeing as it isn't a custom item. any help is appreciated
