I don't mean a blacklist where it will not download files with certain tags. I mean the option to create a list of tags that will be ignored when gallery-dl names the file.

For instance when using
filename": "{tag_string_artist}_{tag_string_character}_{tag_string_general[b:180]}_{num:>02}_{id}.{extension}",

It will download the image tagged with lets' say "1male, armor, knight, sword," it will only include "knight, sword" in the filename.

A whitelist option would be fine as well, were it will only include whitelisted tags in the filename.
