Can we specify region or country to pick up the alerts?

Ex. Dengue outbreak

would like to track dengue out break in a specific country… if i filter before it searches… it saves resources and can pick up faster than it would pick up if it was set to the whole online space.

if i were to pick up all the news then it just creates more noise to filter out to what is really useful…

i know the filters work… but isnt it less work if filter is placed before the search?
