[itsm] customer_company table

Hi there, Does anyone know what "customer_company" table is supposed to be used for? It does not seam to have any link with the "CompanyTicket" feature that is using "MultiCustomerIDs" field in customer_user table. By the way, has anyone used that "CompanyTicket" feature in real life? I mean, if you have 20 "customer users" in a "company", and you want them to see each other tickets: - you need to update CustomerIDs field of each customer user with a list of 20 comma separated IDs . - If ever you need to add a new 21st customer user to this "company", then you need to update all existing customer users records. This is simply not manageable...or am I missing something? Thank you. Madani.
