Alerts for page including subpages

Is it possible to do a one line alert rule that alerts on red's on a page and its subpages. Our main page shows all the sites and every site is split into the same subsections. For some they are quite small but with quite a few subpages so I just want one alert for everything on a site. Is that possible without listing all subpages?

Thanks,
