I love setting location based reminders in Google Now. I can set a reminder for when I get home or the next time I'm at the grocery store. But one thing I can't figure out is how to set a reminder for the next time I'm at a saved location in Google Now. For instance, Google Now knows I go to my parents so it saved the address in Google Now and I renamed it to "My Parents". But I can't set a reminder by saying "next time at I'm at My Parents, remind me...". Is this just a limitation or is there a way to do this?
