Since version 12, "Preferences" allows to set the default Summary Statistics in the output of "Distribution". This option should be effective to all platforms.
I'm not sure I understand your suggestion clearly. Can you give an example where the Summary Statistics preference should be used outside of Distibution?
Example - in ANOVA tables, the "Sum of Squares" and "Mean Square" values make these tables wider and consequently more horizontal scrolling is needed (or more printed pages), and because I rarely need these values, they should be presented only upon special request, not as a defaults. Another example are the 95% upper and lower limits of the confidence interval of each mean produced by Fit Y by X.
