st: stdf after nl

after a linear regression estimate it is possible to obtain the standard deviation of the forecast with
.predict f, stdf
it means the 95% confidence interval for an additional observation.
Is it possible to obtain an equivalent postestimation value after a non-linear estimate, for example after the "nl" command?
With "predictnl ..., ci()" I get only the confidence interval for the (central) line of the means. It is a narrower area.
Thank you for your patience.
