Yep, when you make the order you choose how you're going to finance it and you just put lease (there's a few details to fill in after order is made - log into your account) - and the order will just be stuck there until you've given your RN to the lease company who then get in touch with Tesla to confirm they're taking it over.
Until then, if Tesla contact you you can just tell them you're not ready to take delivery.
I second this, most lease companies have no problem doing this. Fairly normal
