[otrs] Auto filled fields

Hello all, Is it possible, while creating a customer account, to generate the login based on the first name and last name (for example) just entered ? But I still want the field to appear so the agent creating the account can tell the customer what's his login... -> that will help the agent while allowing him to change the login if necessary Another similar need : when an agent chooses a customer while creating a phone-ticket (by clicking on the "customer" link and searching it in the database) it auto-fills the "From" field with the first-name and last-name of the customer previously selected -> that will help the agent but also allow him to change the "From" field if necessary Thanks for your help ! -- Florian
