Yes. By "switching", I meant relabeling the Level 7 as Attachment and Level 8 as Appendix in the list style of the template copy to be used for the specific project.
We keep a master custom template locked safely away from meddlers. Each project starts with its own copy of the template, which is adjusted, if necessary, according to any submission requirements for the documents made from it, e.g., font, font size, margins.
