weird pdf bookmarks question

weird pdf bookmarks question

[Taco Hoekwater]

Hi all,

I have a question about PDF bookmarks. My Document goes like this (heavily simplified):

\setupinteraction[state=start]
\placebookmarks[chapter,section][chapter,section]
\setupinteractionscreen[option=bookmark]
\starttext
\chapter[item1]{Overview}
\startitemize
\item[item4] bla
\stopitemize
\chapter[item2]{Two}
Greetings!
\chapter[item3]{Three}
I don't know
\chapter{Four}
Oh no.
\stoptext

Now, what I would really like is if the link in the bookmarks for 'Four' jumps to the first
page (where the 'item4' reference target lives) instead of to the fourth page (where the 
chapter header lives). 

The question is: is this possible, and if yes, how? To further complicate things, this
is an old project that uses mkii, so lua-based solutions are not helpful.

Thanks in advance for any pointers,

Taco

technically we can have links as booksmarks but then the question is 
what interface to use

lucky me that mkii is frozen

maybe mess around with lists .. but what is really needed is some 
overload of a page .. here's a starting point

\def\RemapBookmarkPage#1#2%
   {\setvalue{RemapBookmarkPage:#1}{#2}}

\let\normaldoPDFbookmark\doPDFbookmark

\def\doPDFbookmark#1#2#3#4#5%
 
{\normaldoPDFbookmark{#1}{#2}{#3}{\executeifdefined{RemapBookmarkPage:#4}{#4}}{#5}}

\RemapBookmarkPage{4}{1}

Of course one needs to hook earlier into code but the principle is the same.
