PDFsharp & MigraDoc Foundation

I am trying to create a multi column page using MigraDoc. As mentioned in other posts, that is not supported but as a possible workaround https://www.pdfsharp.net/wiki/MixMigraD ... ample.ashx is suggested. I have tried this and found that i can use the PdfLinkAnnotation to work on Hyperlinks I insert with MigraDoc. The problem I face is that with this approach my table of contents would display the wrong page numbers, so I was wondering if i could build the table of contents with PdfSharp instead of MigraDoc. When trying this i couldn't figure out how to get the page numbers of my bookmarks I added in MigraDoc. Is this possible somehow or is there a better way to do this?
