Report untracked days

There are just some days when it becomes really impossible to make an accurate estimate of your calorie intake. Often, customers simply leave that day blank. To the coach, this appears as shown below, and they’re left guessing what impact that day had on the rest of the week.

Perhaps we could consider a system where the client can indicate that they didn’t track their calorie intake but specify whether it was either A) A reasonable day (no crazy things or outliers), such as eating with family. Or B) An excessive day that may have significantly disrupted the weekly energy balance.
The customer could potentially indicate this the following day in the morning log. (Smileys, thumbs-up icons, colors, a scale, etc.)
