Publisher TOC to include heading and author

[DanB]

I've set up a standard TOC  that just includes Heading 1.

My article title is heading one, and under this (no style at the moment) is the author's name:

My article title

Author

The TOC currently shows:

My article title                               <page>

I would like my table of contents to have:

My article title - Author               <page>

Is this possible without changing the article title to include the author's name? 

I'd be grateful for any advice
