Yeah, the S and X (unless that's changed also for new ones) is unlimited documents. Not one slot for each type, which is what it sounds like you have. At some point they will contact you, and you can email it to them then. Some of that they don't need until after delivery, anyway, as they won't be dealing with the DMV until then. Nothing happens or is actually really needed in advance, except maybe that you have insurance (and even that is only if you are financing through Tesla).
