Django-Filter how to Customize Behaviour of All CharFilters?

Using Django Forms & APIs

I want to make the default behaviour of my CharFilters that they have the accents removed for comparison. How can I do that besides manually applying a method to each one?


    title__icontains = CharFilter(field_name='title', method='unaccentFilter')
    publishers__name = CharFilter(field_name='publishers__name', method='unaccentFilter')
    developers__name = CharFilter(field_name='developers__name', method='unaccentFilter')
    platforms__name = CharFilter(field_name='platforms__name', method='unaccentFilter')
    genres__name = CharFilter(field_name='genres__name', method='unaccentFilter')
    engine__name = CharFilter(field_name='engine__name', method='unaccentFilter')
    websites__category = ChoiceFilter(choices=STATUS_CHOICES)
    similar_games__title = CharFilter(field_name='similar_games__title', method='unaccentFilter')

    class Meta:
        model = Game
        fields = {
            'title': ['iexact'],
            'summary': ['icontains'],
            'release_date': ['iexact', 'range', 'gte', 'lte'],
            'category': ['iexact', 'icontains'],
        }
    
    def unaccentFilter(self, queryset, name, value):
        normalized_value = unidecode.unidecode(value)
        return queryset.annotate(unaccented=Unaccent(name)) \
                .filter(unaccented__icontains=normalized_value)
