Отправка многостраничных запросов в mule

У меня есть соединитель базы данных из выбранных данных, которые я использую для создания файла, и я хочу сделать HTTP-сообщение с файлом (созданным из выбранных данных в csv) вместе с другими данными (текстом), как показано на скриншоте. Согласно документации mule, полезная нагрузка должна быть исходящим вложением, что я делаю с помощью свойства Set Attachment. При таком подходе я устанавливаю Content-Type для одного из моих вложений как application / CVS (поскольку мой файл имеет тип CVS) и как text / plain для другого параметра. Есть мысли о достижении этого? Я приложил скриншот того, как запрос выглядит в Почтальоне.

Ниже приведен XML-файл конфигурации .. !!
