Работа с дополнительными свойствами в HostCMS v. 6

Необходимо добавить свойство для пользователей сайта, которое будет определять другого пользователя сайта, так сказать «родителя». А так же нужно доп свойство для групп и товаров интернет магазина для привязки к конкретному пользователю. Было бы просто замечательно, если бы это выводилось выпадающим списком в админке. Как это можно сделать??
