What’s the preferred way to call out a tapered pipe thread (internal) with gd&t?

I had never heard of gd&t till this last month. It was discussed in the CNC Machining part of this forum. You might find the same post gets more answers there.
Here is the first thread that I remember even seeing the term:

Just a suggestion that works for us. A callout indicating that the pipe tap should be driven until just 6 full threads are left on the tap. This gives us just the right thread size on 1/8” to 2” pipe taps.

What does that gauge look like and where would I find one? Is there some kind of G0-No Go feature or just one size fits all? Photo?
