Why Can't I Add More Than One Sub-City To An Automarketer Campaign?

​If you select one sub area of a city, such as Los Angeles, it automatically scrapes the entire city.

Scraping of Specific sub areas is not supported at this time.

I know it's confusing, but selecting any of the sub areas tells the system to scrape all of them.

That's why the system is detecting the other sub areas as duplicates and removing them.
