For example, I want to have the habit of "Creating" each day - whether that be writing, photography, or videography. If it's a rainy day, it may be best for writing OR I may spend time with both photography and videography. I'd like to color-code the subcategories so that when I look back at the "Creating" habit calendar, I can see how I split my "Creating" time over the past month (in addition to how many days I was successful at incorporating "Creating" into my day).
