Permitir subdominios de dominio bloqueado en onebox

Lamentablemente, no creo que eso sea posible según este tema:

How can I block specific links from oneboxing?

I’m trying to preserve the oneboxing of the homepage of a specific domain, but prevent the oneboxing of any thing more that that. i.e. mydomainofinterest.com makes a onebox mydomainofinterest.com/anything does not Is this achievable? I can only seem to block an entire domain - which would be fine if I could get the homepage of that domain to still make a nice onebox.
