I have a design guide with a complex table of contents (see toc1.png).

There are topics like “Head - und Subline Allgemein” (see toc1.pgn) which spans over 3 different pages. After generating the TOC the topic is listed 3 times followed by their associated page number (see toc1.pgn).

I would like to see a check box in the table of contents dialogue box which merges all the same instances into one followed by the page range number (see toc2.png)!

Perhaps with a control of what character separates the two page numbers.
