Re-linking endnotes to reference numbers

[AaronMo]

Hi All,

First I should point out, I'm brand new to Sigil and CSS. I've created an epub in Adobe inDesign and now I'm trying to move the endnotes to the end of book rather than end of section/chapters. Maybe this isn't the correct process but what I did as a test is cut the endnotes from the first section of my book and paste them into a new section I created. It seems to have worked. The problem is the links from the reference numbers to endnotes were broken. However, the "round trip" links from endnotes back to the ref. numbers still work.

Two questions. Is there a more efficient way to move the endnotes? They appear in three sections of the book. How do I fix or add round trip links?

Thanks,
Aaron
