Please note, that Step does not contain any history, so no program can make parametric changes to previous development steps.
O.T. - but maybe interesting:
Direct-Modelling CAD program do not have/need a history. For these programs STEP AP203/214 is enough to change every part of the model. Some history-based CAD programs now also have some kind of "auto-feature-reengineering" when loading STEP files. Here you can remove holes or change same basic dimensions. Parametric does not belong to history. Direct modeller also use parameters.
Loading IGS-file and change solid with a direct modeller:
