Mistake in DS 160, OFC tomorrow

I have my biometrics appointment scheduled for tomorrow at Delhi VAC and I noticed I made a mistake in my DS 160 - I selected the wrong category.

I created a new DS 160 and there is no way to link it to my application myself. I read somewhere that at the VAC they should be able to link my new DS 160 with my application? Has anyone faced a similar issue? Could it be resolved? If yes, how?

Update: I went to the VAC, informed them I want to update the DS 160, they did that quickly and did not ask any questions.
