usage of CATPCA on both ordinal and nominal variables at once

In my data set, I have both nominal and ordinal categorical variables.
for eg: subject stream(PS,BS,IS,MB), level of satisfaction(HIGHLY SATISFIED,SATISFIED,NEUTRAL,UNSATISFIED,HIGHLY UNSATISFIED), gender(MALE,FEMALE), etc..

Shall I use CATPCA on that dataset?
If so,how can I select "optimal scaling levels"? Do I have to select optimal scaling levels separately for nominal and ordinal variables?
