Weekly totals

Is there a function on the food log that totals your calories for a certain date range?

i.e. I want to see how many calories total I've consumed per week.

Is it there and I've missed it, or would I have to add it manually for now? 

If any of the CC developers are reading this it would be a GREAT tool to have. 

If you go to the analysis page, you can change the date range, and it will show you the averages for the range you've selected.  I don't know how you can get a total calorie score, though, without multiplying that average by 7...

The page lays out the total calories for each day without all the separate entries so that at least makes it easier to add up. Thanks!
