Grouped/simplified country blocking and export/import feature

Country blocking seems a great feature for sites that only want legitimate traffic from certain countries and the possible traffic loss of is outnumbered by the security gain.

However country blocking is not very user friendly right now. The list is large and time consuming to edit. If you manage serveral sites it can become a nightmare.

Would be nice if countries were grouped (by continents, security ratings, or similar) and that profiles could be exported and imported making changes to several sites quick and easy.
