Trying to fill a bottle with a custom fluid without it being a water bottle

So I'm trying to make a bottle be able to interact with a custom fluid where it doesn't become a water bottle. Like when a glass bottle interacts with custom fluid it becomes a water bottle but instead turns into a bottle holding that (custom fluid). I already have a bottle of (custom fluid) made and I have it where if I drink it, it turns back into a normal bottle. Any help works, I'll also be trying to solve it on my own since there's no videos about it.
