Google Now Shopping List?

[tuz]

Just got my HTC One with Google Now, which is very cool for having directions ready when I need them and things like that. I see that it shows me movie times when I'm near a theater and other things that are similarly cute and neat but not all that actually useful (though the post office I'm going to is next to a movie theater that rarely means I want to know movie times). What would be the greatest possible thing is if my phone could tell that I am in a supermarket and have my shopping list (which I have as a google tasks list that is currently in a gtasks widget on my homescreen) show up on my LOCK screen. Is there any way to make this happen?
