Default folder + keywords in command?

[AldebaraanMKII]

how do i set it up so that the folder the files are downloaded is:
{artist}\{artist} ({date:%Y-%m-%d}) ({gallery_id}) {title} ({language})

but the base folder is:
F:\Temp\Downloads\Hitomi

so that it becomes:
F:\Temp\Downloads\Hitomi\{artist}\{artist} ({date:%Y-%m-%d}) ({gallery_id}) {title} ({language})

and the filename is:
{artist} ({date:%Y-%m-%d}) ({gallery_id}) {title} ({language}) ({num} of {count}).{extension}

Also it is possible to add that as a argument to the command itself? I don't want to use the config in this case.

(I replaced {artist} with {artist!S})

{
    "extractor": {
        "base-directory": "F:\\Temp\\Downloads\\Hitomi",
        "directory"     : ["{artist!S}", "{artist!S} ({date:%Y-%m-%d}) ({gallery_id}) {title} ({language})"],
        "filename"      : "{artist!S} ({date:%Y-%m-%d}) ({gallery_id}) {title} ({language}) ({num} of {count}).{extension}"
    }
}

is it possible to add that as a argument to the command itself?

-d "F:\Temp\Downloads\Hitomi" -o directory="[\{artist!S}"\", \"{artist!S} ({date:%Y-%m-%d}) ({gallery_id}) {title} ({language})\"]" -f "{artist!S} ({date:%Y-%m-%d}) ({gallery_id}) {title} ({language}) ({num} of {count}).{extension}"
