moving button position .._cart_button instead of .._cart_form

Hello Sir.
Thank you for awesome plugin.
I hope to move the position of ‘Buy Now’ button next to the ‘Add Cart’ button.
I’ve tried to add button by short code into simple.php, but it doesn’t add correct quantity.

I’d like to move the ‘Buy Now’ button inside of ‘woocommerce_after_add_to_cart_button, instead’ of ‘woocommerce_after_add_to_cart_form’.

Thank you in advice.
