I came here looking for information about this, too. I tried both methods of using the new name for Hasty Touch II and the macros wont validate them as a valid option.

You can even just type /ac "Hasty Touch" into your chat bar and see that it says "Only available while crafting." come up on your screen, but type /ac "Hasty Touch II" and it will give “Hasty Touch II” is not a valid action name.

Wondering if this is a bug after all or if we're missing something.
