Using SDK to create a PDF from Excel with internal document links

Hi. 

I am trying to use an excel macro to union a collection of PDFs into a master PDF, and create an index at the beginning of the master PDF based on a table from the worksheet in excel. One of the things I need is to create internal document links that can allow a user to click a link the PDF's index that will take them to the page number for that index section. Is this possible using the SDK? I can create the master PDF just fine using the PDDoc methods (InsertPages() etc ), but know how best to approach the links.

Any thoughts would be appreciated.

Thanks,
