Yeah, you can't just change unless Tesla initiated it. In my case, I ordered Performance 7 seater when it was announced. Tesla contacted me In late Jan 2021 to change to LR 7 seater or Performance 5 seater. I wanted LR 7 seater and add the tow hitch (not an option when I ordered). However, she said it cannot be done w/o triggering the whole reordering. They already have pre-configured "equivalent" changes for people who ordered Performance 7 seater to LR 7 seater with 20 in wheels. If you don't like it, you just have to reconfigure the whole thing with current pricings.
