Use shipping method instances?

it works with generic methods available in woocommerce, if you create a variation of the method, then plugin might not see it as a separate method and you won’t be able to target it.

Thanks for the answer. The plugin works well, so that’s disappointing. I’ll have to find a solution that uses instances.
