When adding tags manually, there's an option that auto-replaces old siblings with new siblings when you enter the old sibling, but it can be disabled, and I do. How do you disable that for tags that are automatically added through the gallery downloader. I checked the tag import options, but I didn't see anything about siblings there.

I'm importing files from Sankaku Channel, and I want the tags that are imported into Hydrus to be the tags that are there exactly as they are on Sankaku Channel. For example, I have 1boy as the old sibling of "1 male" in "my tags" but when I import a file from Sankaku Channel, "1boy" is just replaced by "1 male" entirely. I don't want that to happen. I want the underlying tag that's imported to still be 1boy, even though it will displayed as "1 male" since it's the old sibling.
