Filter via query string

We’ve added a KnackHQ database via iFrame on one of our sites. There’s just one
search field: country.

What I’d like to achieve is a link/URL for selected countries.

For example: http://www.example.com/KnackHQ?country=Germany

By using this URL, the
search field is automatically set to Germany and the corresponding database
entries are displayed.

Would be a great feature and nice if you’d consider adding it.
