[otrs] randomize password for new customers

Hello, I have a little question. Perhaps I havn't found the feature yet or there is a little modification to do. What I want is to generate a randomized password for new customers and to send it to them automatically after they are saved I think it should be sth like the lost-password-function, but generated manually by an agent when he saves a new customer. Is there a possibility to realize this? Thanks in advance Markus Nagel
