Can Image's Have Their Metadata Retained When Downloaded?

[CivilizedCiv]

I don't know if I am doing something wrong, but I would like it if at least the published date an image was posted to its original source site (Patreon, fanbox, etc.) can have that date included somewhere in the metadata (Modified field, as that is what gallery-dl uses so there may be a good reason for that) for when ktoolbox downloads it.

For example, if an image was posted on Patreon user SteveLake's account April 3rd, 2024. Kemono then scrapes that post and stores it at some point in time. Then I come along and use ktoolbox to download that image. I want that April 3rd, 2024 date to be included somewhere in the metadata of the image (Probably modified metadata field). I do see that the post.json "published" value is what I think I want for date metadata, but that is solely in the post.json file, not included in the image.
