I have made an epub file with a large table of contents. It contains many songs and the start of each song is listed in one or more entries in a table of contents.
This is a nested table of contents which works well, for example a section for favourites, another for blues etc.
I can expand any section and see the songs in that group (eg. blues).
So a single song may appear in more than one section of the table of contents. The song page however only exists once in the body of the epub.

When i use the table of contents, for example the blues section, i click on the song i want and all is good.
Now i want to go back to the table of contents, but still be in the blues section of the table of contents.
Re-opening the table of contents however takes me to the correct song however displayed within a different portion of the table of contents.

I tried using an iphone with dropbox, using the builtin epub viewer of dropbox. Here is seems to work as i expected and returns me to the
correct section of the table of contents.

Is there any way i can return from the page back to exactly the same place in this type of table of contents?
