[dev] Customer User Management

Hi, Is there any way existing to pre-select some fields when adding a new Customer User please ? We're using the direct link : http:///otrs/index.pl?Action=AdminCustomerUser&Subaction=Add&Nav=Agent&Source=CustomerUser to be directly logged in on the Add a new Customer User form. I would like to pass some variables through the URL to auto-select CustomerID field or pre-filled Email field e.g. Is it possible please and how ? Thks, best regards, Laurent MINOST
