American Amber Water Profile

I use RO water for brewing and make chemical additions to match the style beer I am brewing.  From your water profile list, what would be good city water to emulate for an American Amber Ale?  I wish there was a calculator that would provide chemical additions for RO water by picking a certain beer style instead of choosing a city water profile.
Thanks,
David
