Minitab Power and Sample Size: selecting a non-Wald interval method for one-sample proportion tests

Power and Sample Size interval method configuration

I am using the Stat > Power and Sample Size dialog in Minitab (recent desktop version) for a one-sample proportion test. The dialog appears to compute its confidence interval using the default Wald method, and I cannot locate any option in the graphical interface to switch to a Wilson score or exact (Clopper-Pearson) interval.

My concern is that the planned sample sizes are small and the expected proportion is close to zero, a situation where the Wald interval is known to undercover. I would prefer to keep the entire workflow inside Minitab rather than exporting to an external script.

I am aware that the Session Command Language may expose an interval-method subcommand for the Power and Sample Size command, but the documentation I have found gives few concrete examples, and I am unsure whether the behavior is consistent across Minitab versions.

Is there a supported way—via dialog option or SCL subcommand—to make Power and Sample Size use Wilson or exact intervals for proportion tests? If SCL is required, what is the correct syntax, and does it apply to both sample size and power calculations? Are there version-specific limitations I should verify before relying on the output?
