Hello, I know this is old and I'm new to all this, but where would I implement this code into the cart-shipping.php?

I would also be grateful to hear from you on how to implement this. I came here via https://wordpress.org/support/topic/shipping-titles/#post-4967609, and I am looking for a way to rename the split shipping packages.
