Perturbation That Preserves Ordering

[kjam]

Is your feature request related to a problem? Please describe.
It would be nice if I could preserve ordering and still allow for minimal perturbation - for example, for time series related data.

Describe the solution you'd like
Is there a way to allow perturbation to be stateful or to take into consideration the constraints of time-series based data or other data where increasing or decreasing values are significant?

Describe alternatives you've considered
You could add another column with a simple ordered index and use that as a work around.
