Reset Preset Ratings

Dear Fellow Nuendo-users,

Does anyone of you know how to set ALLthe preset-ratings to zero stars at once?
I’d like to add my own ratings to the presets, but Steinberg and other manufacturers were so kind to add their own ratings to most of their presets so I need to reset them to zero stars before I can add my own stars to them.

Any help welcome, thanks in advance!
