Does Serentdipity have plugin that auto set nofollow on link

[cyberman]

Plugin like smart seo link on wordpress. It will add rel="nofollow" on link in every entries. How can I auto set nofollow on every link in post in Serendipity? It's very tedious work to edit manually.

Thank you.

You noticed it destroys the idea of the internet or at least of blogging to set something like this automatically every time?
