PDFsharp & MigraDoc Foundation

Hi, this is my first post so please bare with me.

I needed the ability to be able to draw out some information on a pdf. Therefore, I created a PdfDocument and used the XGraphics object to draw information to a few pages.

However i now need to append more information to other pages that should be appended onto the PdfDocument created previously. The problem here is that I cant use the PdfDocument object as the string I am writing to the page is unknown. Therefore I needed to use Document as you can use the pdfDocumentRenderer to add sections and paragraphs to your page, which will automatically create a new page if the information overruns from say page 1 to page 2.

Is there a better way to go about doing this rather then trying to concatenate two documents together?
