Design request form to show custom fields.

We have a template that ask some customer questions for new software request. We want this to go to a Request items, which it does, but we cannot view or edit the details. If we convert it to a request, we can edit and see the details we need from the custom list which were generated from the Service Record field.

Does anyone know how to design form for the request tab? We want to customize the order and the items in red. There is no form button in the upper right like the incidents tab.
