Refinement of loading product filters

Improvement is needed, which would allow loading product filters as fields in the product import, and not through the add. settings So that filters can be selected from a drop-down list http://joxi.ru/RmzZ0ZPCYnONym not with additional settings http://joxi.ru/YmEMWMQFwo3x0m The fact is that there are suppliers in the file whose filters are indicated simply as the top line - the name and the columns below - the values In boxing, now you need to load as the entire column with the name of the filter, and the next column with the value.
