How can I modify the appearance of Windows 10 calendar app?

  appearance, calendar, windows

I’m looking for a way to modify the font style of the "day" numbers in the calendar pane that pops up from the taskbar in windows 10, in response to an event being set on that day.

If the font style could be set to bold, this would in effect highlight any upcoming days with events in the "month" calendar view, something I’m sure I’m not the only person that would find useful!

There is no way to do this in the settings so would require some kind of re-coding of the app… I’ve no idea if this is possible but thought this might be the best place to ask.
