Category Specific Attributes Setup – Feature request

Please add option – No attributes
This would be particularly helpful in my set up
At present categories can either have – all or select from existing attributes list

Found this following code in your help guides but the english is not quite clear enough to be understood clearly
add_filter( ‘wcfm_is_force_category_attributes_mapping’, ‘__return_true’ );
Would adding this do what I would like to achieve?
