Table of contents - independently change format of entries and occurances in text

[enso]

I have a long document with headings, and a table of contents at the start of the document, with the entries being links to that section. So far, so good. However, I also want the toc text to be single spaced, with no before/after additional spacing.

I've tried using both Heading styles and TOC styles.



If I change the format of the Table of Contents, the next time I refresh the table, the formatting reverts. __FAIL!
If I change the format in Table of Contents > Modify, then the text in the document also changes. __FAIL!

Is there a way to accomplish what I want? Would using an Index instead of a toc do what I want?
