Colored dots for each calendar in month overview

When in week view, there is a possibility to extend the days indicator above into an overview of the entire month. In that view, there are colored dots indicating which days have events planned and which are free. When using multiple calendars, it would be useful to have one dot per calendar (ideally of the same color as that calendar) to know at a glance if I have a work event, a personal event, a family event,... instead of just knowing that a have an event planned without knowing what type. In summary what I am asking is to do things closer to the way Google calendar does it, or at least include a toggle to switch between the two behaviors. I included screenshots of both OfficeMail and Google calendar for comparison. Thank you.
