Okay.

We didn't either back when we did this. We just followed whatever
the steps were that the Ubuntu downloads page linked to for creating
a live USB drive.

I guess I'm not understanding what's wanted, then. We just took our
live USB and copied some files onto it next to what was there. We
didn't know it shouldn't work. That was several years ago and I have
no idea whether it would work nowadays, but am willing to experiment.
I need to do an installation soon, so I'll try copying a couple of
files onto it when I do that. I've got nothing to lose but a little
bit of time and, from what you're saying, I should quickly find out
that it won't work.
