[1.12.2] Registering UniversalBucket Liquids to OreDict?

[Tschipp]

I'm adding several different milk fluids, and I'd like to add the milk buckets to the OreDictionary.

However, I've found that it doesn't care about NBT of the UniversalBucket, only about meta (and item name ofc).

That means that all UniversalBuckets get registered to the OreDictionary.

Is there a way to only register my liquids, or is it not possible (without having to create a new bucket item)?
