NPT Threads

I need to call out an external NPT thread on a drawing. I can just make a note, but I was hoping that I would be able to add a feature to my model that would help me with the specifics. I can't find NPT threads in the cosmetic thread feature or the thread feature. Am I missing something? I feel like this should be easy. I've found a lot of posts about people modeling the thread so that they can print it, but I don't need to get that complicated. Advice appreciated.
