As you noted, the file that must appear in the sudoers configuration is the one that is launched by sudo, and not the one that runs sudo.

That being said, what we often do, is having something like

user ALL=(ALL:ALL) NOPASSWD:/path/to/script.sh

in the sudo configuration, where script.sh has all the commands that the script has to do.

sudo /path/to/script.sh

The only issue is if some commands must not be run as root, you need to insert some su - user -c "command" commands in the script.
