Export PDF from arcmap to include a pdf link

Hi there:

I was doing a project that needs to export a pdf map from arcmap. The export works fine, we used the python script and created a .net addin with it.

But there is one additional request from client: they want to have a pdf link for the target points in the pdf map. I know we can add the pdf link in acrobat manually by using bookmark and set link function in adobe pdf writer. My question is: is there a way to add a link when we export the pdf from arcmap?

I think i can read a pdf file using itextsharp and add link from there, but the difficulty is to location the point in the pdf map.

Any suggestion and hint is really appreciated.

Thanks.
