I have an existing application that uses the Apryse (PDFTron) .NET PDF Library for Windows and want to port it to use your library.

I have a document that consists of personalised "front" pages for sending by post.
We need to insert a common page of static information (so it becomes the "back" page for each front page).
The personalised pages come from document A and the boilerplate content comes in a single page document (document B).

I have successfully created a new document (document C) by iterating each page in document A and inserting it in document C using Import pages followed by importing the first (only) page from document C until all pages from document A have been imported.

This produces a significantly larger file compared with the Apryse version.

In my original code, I was able to "reuse" the back page rather than having multiple copies of it in the new document (I think of it as pointers to a common page).
Is there a similar concept with your library?
