Missing value handling for Ordinal variables in Partition

Suggestion:  Please treat missing data (and missing value code data) for ordinal X/Factor variables the same as continuous X/Factor variables when the informative missing option is selected.  That is, test to see if missing is better grouped "high" or "low".  Right now, it appears to be treat the missing value (or missing value code) as an ordinal value and assign it accordingly.

It appears to work in JMP 16 when the dependent variable is continuous, but when the dependent variable is ordinal, it appears to just put the missing value category of the ordinal predictor variable with the low category group in the split.  So, I think this is still an open ask.
