Food suggestions for specific nutrients

I became a gold member in part because I thought that "suggest foods" was going to be specific to nutrients rather than to overall gaps in the day. (I'm still happy with the service, mind you! I like being able to divide up the day, e.g.)

I would love to be able to hover over, say, cystine, and have cronometer point me to a list of foods I could eat, ideally ranked by highest to lowest sources. Yes, google is there, but it would be great to have this integrated.
