How many keywords does this track per domain?

Can you track multiple Regions? for example i Use 5-25 Data centers including tracking Google Upper East Side by Zip Code and Google Maps by the sam zip code, then from other locations - Google Financial District, and Google NJ and Google in Miami? BOth Maps and Organic. I need to do this for multiple accounts; sometimes we track from 10-15 locations (organic and local maps) and the app is emulating the regions. Is this possible? Limits?

Thanks
