Would it be possible to add support for external json files saved using https://github.com/dnsev-h/ehentai-archive-info, with the same name as the archive?
Example:
[GRINP (Neko Toufu)] Onii-chan wa Oshimai! Tokubetsu Hen [Digital].cbz
[GRINP (Neko Toufu)] Onii-chan wa Oshimai! Tokubetsu Hen [Digital].info.json
