Rate the contactor filter by Holding Company

Good afternoon! https://crm.hlr.ua/ Need an assessment of the refinement of the contact filter Company [file]8853[/file] (or another one at your discretion). It is necessary to be able to filter contacts by Holding (by its name or id) and see all contacts associated with this holding, that is, there is a company https://crm.hlr.ua/admin/shop/users/69350/, if I filter by name [file]8854[/file] should see all the cards http://joxi.ru/GrqaWYguROxY3r, it is also important that the group filter works. That is, if I filter by the name of the holding as above, and select contacts Without a group http://joxi.ru/E2pZ6egH41xbbr, then as a result I will see only three contacts [file]8855[/file] for which the group is not filled Please rate. Thanks
