Adding a separate word document as an appendix

We are create user documentation for a new Business Central App we have created and Clicklearn is fine for 90% of what we have needed. The issue I have run into is that I have an Appendix sections which explains the theory and examples of the embedded calculations that run in the background. I cannot record the theory using Clicklearn but want to rather embed the word document (10 Pages) into my project so when I publish or produce it includes the word document at the end of the document.

Have not found a way to do this.

Note that I have tried using the Notes functionality but have found that this does not support what I need to do as cannot format effectively and is very time consuming.
