Night 1 and 2 presale

I signed up for the presale code for Night 1 in San Diego when he announced the tour and recently received my code via text, I think I want to do both nights now but have not signed up for the presale for night 2 yet, am I still able to do it? Sign up for more than one event. I don’t want it to affect my presale for night one like void the code or something. Thanks.
