[Plugin: WP Nofollow Post] Nofollow only a specific domain

Hi,

I want my external links to be nofollow only for a specific domain.
It’s the affiliate links, actually.
It would be much easier to blacklist one domain and all links to it to be nofollow (old ones too) than to whitelist tens or hundreads of domains.

Is that somehow possible?

Thanks.
