Multiple Opt-In templates for different campaigns


i need a was to define Opt-In email templates on a per campaign basis.

In /modules/EmailMan/controller.php I see “$configurator->config[‘email_confirm_opt_in_email_template_id’] = isset($_REQUEST[‘email_template_id_opt_in’]) ? $_REQUEST[‘email_template_id_opt_in’] : $configurator->config[‘aop’][‘confirm_opt_in_template_id’];” , which I think is used for retrieving the template, but I need it on a per campaign basis. Any idea to to it?

Alternatively, is there a way to send out opt-in mails based on language?
