Set primary calendar in calendar widget

I really like the calendar widget. I have several calendars connected from Google Calendar, and while I can filter which ones are displayed, I would love the option to set a specific calendar as the default one shown in the widget (without having to tap the calendar each time to see it).

Right now, Niagara seems to decide which calendar is shown first, but it would be very helpful if you could either define a "primary calendar" to always appear as the default in the widget, or customize the order in which calendars are displayed.

Thank you for your great work.
