[otrs] Customer frontend select ticket customer ID when creating a new ticket

Hi, Anyone here who succeed to achieve this kind of behaviour please ? I would like to add a drop down menu under CustomerTicketMessage (New Ticket form) displaying the two values of CustomerID and CustomerIDs for the current logged in customer user so this one will be able to choose for which company he is opening the ticket. This will avoid agent/administrators to re-affect ticket customerID (company) if it was not the main one for the customer user and automate a little bit more the process. OTRS defaults to open the new ticket with the main Customer ID of the customer user who opened the ticket. I'm available if I was not clear or if you need more informations. Thanks a lot.
