New Post: Render partial PDF

I have a pdf document that I am generating using MigraDoc. It has "Header", "Footer" and content. It works and does what I need but now I need to insert a basic HTML inside the content. I something like this possible? It would be awesome to have a extension AddHtml to MigraDoc. I will try to take a look at the code to see if I can do something like this but if there is already a way of doing this I would love to know :)
