I am experimenting with adding the QSA and Supplementary roll pages in PDF format to the relevant unit page.
Here is an example for Ashburner's Light Horse:
angloboerwar.com/unit-information/south-...rse?showall=&start=2
One issue with this approach is that the file sizes are large which will make opening the PDFs slow if the internet connection is slow. For example the ALH PDF is nearly 15MB in size.
One way around this would be to slice up the PDF into smaller chunks but this could be quite time consuming. A potential downside of multiple files is that you would have to look through all the files to search for an entry.
I will continue to experiment and see what is possible/feasible.
