[GNC] importing multiple CSVs to Gnucash

[flywire]

I started a thread before the one I linked where I explained I had been
through an equivalent process of adding transfer accounts. David explained
it well in the thread I linked which is supported by
https://wiki.gnucash.org/wiki/images/8/86/Gnucash_erd.png and the code.

Bad luck, the developers have designed it so you can't with CSVs.
