I've got some books from archive.org and I've got urls as identifiers, but I'd really like to create my own identifier type with a link and display template
I've got
url:
http://www.archive.org/details/alicesadventures19033gut displays as
www.archive.org
but I'd rather have
archive.org:alicesadventures19033gut displayed as
archive.org and still linked properly with it's own selectable identifier category in the tag browser
I can't find a way to set up a template though short of, I assume, creating and metadata import plugin. Am I missing some method inside of Calibre to do it?
