How do I put comment text from a pixiv post into jpeg metadata?

[Triramama]

This is the only scraping program i know that supports naming file metadata, I read up on the matter in the guide section, I installed exiftool and got grabber to recognize it, but I have no idea how can I use it to batch download pixiv images with author's comment in the jpeg properties, it is possible right? So can anybody help? Ideally, I'd like to copy the comment into the field "comments", which supports indefinite amount of symbols
Nobody cares about comment information except for danbooru but i have no idea what they use

Unfortunately I don't think Grabber has the author comment available as a %variable% at the moment for Pixiv. Other stuff (tags, name, artist, etc.) can be put in metadata though 🤔

I really hope you can add such a feature, Bionus.
You never know what might be in that comment field, it might be useless fluff that with no meaning, but author also very often shares stuff like context of the image, tidbits about it, his ideas, how he made it, etc. There's a big effort to save pixiv artworks but virtually nobody cares about what author has to say, posts from that site get deleted all the time and In my mind it's a big loss that art on many image hosts is preserved without so much as its name let alone its description.
