Instant order creation after Order now button submitted

Is there any possibility for creation of order instantly in shop while submitting “Order now” button in 4th step Order. If possible kindly share your thoughts.

What´s your problem/intend?

I need to create order immediately after order now button is clicked and while success i need to restrict order creation process in shop and update only relevant fields which i need to be updated. Is this possible.

It will be created immediately after submitting order now button …

Not sure if I understood it properly. Is it maybe something like fnc=toBasket?

Yes, that would be possible. After pressing the button “tobasket” it is possible to create an order ID and start “finalizeOrder”.
