Reform chart titles and add subtitle option.
Chart title text is too close to the top of each graph, making it cluttered. It would also be nice to have subtitles with the font size, color, and weight automatically adjusted. The NY Times Fivethirtyeight blog is a good example of effect titles and subtitles. These would both be left-aligned for readability instead of centered. Perhaps the default suggestion could be to have readers summarize the message of the chart, as this is good data visualization practice by professionals.

Chart Templates allow you to preformat a chart the way you like it, then easily reuse that format. https://support.microsoft.com/en-us/office/save-a-custom-chart-as-a-template-259a5f9d-a9ec-4b3f-94b6-9f5e55187f2a?ui=en-us&rs=en-us&ad=us Unfortunately, it doesn't handle subtitles.
