Modify View Template's V/G Overrides Model

[EATREVITPOOPCAD]

Can somebody point me in the right direction here... I would like to hide/show object types in the V/G Overrides Model for a specific View Template, (for which I have the ViewTemplateID)

So I was brain farting a bit while burning the midnight fuel and couldn't figure out that View Templates are the same class as Views...

            UIApplication uiapp = commandData.Application;

            Document doc = uiapp.ActiveUIDocument.Document;
            Selection sel = uiapp.ActiveUIDocument.Selection;

            View cView = doc.ActiveView;
            View viewTemplate = doc.GetElement(cView.ViewTemplateId) as View;

            Reference sourceReference = sel.PickObject(ObjectType.Element, "Select object type");

            Element sourceElement = doc.GetElement(sourceReference.ElementId);

            using (Transaction t = new Transaction(uiapp.ActiveUIDocument.Document))
            {
                t.Start("It's about to hide!");

                viewTemplate.SetCategoryHidden(sourceElement.Category.Id, true);

                t.Commit();
            }
