Why is there an order for "complimentary parking passes"?

Went to the site to look at how sales were looking, and there is an option to select your parking pass. Was I supposed to do that (the time to select has lapsed), I thought they just gave us the best available based on our CP level?

Yes, I think you were. I did.

Ticket office just replied to my email (less than 10 min after it was sent, good job on them), and said I am “all set for parking in our garage.”

They didnt clarify, but maybe this was an option if you did not want the “best” you qualify for, or maybe they added it later, I renewed the first day renewals were available, and this was not something I could sign up for at the time (so the early renewals were all signed up automatically?).
