Currently if I have a EPUB 3 book and if I use the save to disk feature with an external OPF file it creates an OPF file that has package version 2, this means it uses fields such as "calibre:series" instead of "belongs-to-collection", is there a way to make it so that the created OPF matches the EPUB version of the book? (For example uses EPUB 3 fields if book was EPUB 3 or EPUB 2 fields if book was EPUB 2)
