Adding addtional search engines in admin console

I've noticed that the 'out of the box' search engine detection rules misses quite a lot of search sites that are directing traffic to our site (such as search.bt.com uk.search-results.com, search.conduit.com, search.sky.com, search.babylon.com,  etc)

It would be great if within the admin console I could configure additional search engines to be included in the standard detection rules.

You'd need some way of entering the URL referrer and the keyword query string parameter.
