Yes, this is not the use case for Master/Child.

It should work with "includeonly" if you have a Master document that includes
the existing documents source(s) + the new appendix.
After a first run which includes all sources (to get the references right),
you may exclude the main document and re-compile.

However, I would rather print the last 50 pages of the combined document to
a file and upload this.

In any case, you may have to add some advanced LaTeX code to restart the
page numbers etc. or live with the appendix document starting at 801.
