Since they will end up with the same name, sort order is the only way to
specify between them. Its a bug IMHO, but if there are two libraries
with the same named symbol in them, the previewer will preview them both
correctly, but you'll only ever be get the latter one in the list into
your schematic (whichever you choose to place).

If the required symbol were copied to your local project symbol dir,
then that would be the one which is seen and used.

I've wanted this before now.. Hs, edit, save as different name, then
have to delete, and re-place the component.

Peter B is right.. its black magic, but focusing on the user
experience... perhaps something we should consider. A dialog box
perhaps? (Sometimes I "Hs" on a symbol I want to edit, but _don't_ want
to change the instance I started with).
