Option to select which calendars appear in the Menu Bar “See your day at a glance” view

The “See your day at a glance” functionality in the Menu Bar is really useful, but with all my calendars included it gets cluttered quickly and becomes hard to use at a glance.

It would be great to have the option to select which calendars feed into the Menu Bar view. For example, being able to show only work meetings (and not personal or other calendars) would make the overview much clearer and more practical.
