I am bound by a prescribed format in one of the documents we create. If it was up to me, I would use...

(as a heading 1), but the required format is...


In order for this to show up correctly in the TOC, I use the first format shown above, but right after Attachment 3 I use a line break, then after the em dash another line break.

In the end it looks like...


All of this I make heading 1 and it shows up in the TOC just fine. I also make the em dash white font so it doesn't actually show in the doc.

Again, bound by a certain format, can anybody think of a more reasonable way to do this?
