Can I set a custom address for reminders in El Capitan? I want to get a notification to buy something at store I only rarely go by. "Reminders" doesn't seem to know the store name but I can find the address on Google Maps no problem. But I can't seem to enter that address in the El Capitan "Reminders" app.

Does anybody know how to do that?

Thanks! :-)
Just start typing.
It will search Contacts, recent locations, even what appears to be a Bing/Google search for matching locations.
Click it in the list once you've narrowed it down far enough.
