Filter Subcategory
A filter group nested under filter and used for creating deep hierarchies of filters.
A filter subcategory is a filter group that is nested under a filter. It is a human-readable heading used to describe and contain additional filters within. It is not itself a filter, but it does have an optional filter prefix that is appended to filters in the subcategory and that acts like filter for organizing filter label names.
