Marks in calendar

Hi, there. It would be lovely to see a mark in the calendar when you have something planned or a property related to that date. (For example--> property Calendar in my "to do's" objetc: 1/1/2022. / At calendar: a small coloured dot under the number's date in the calendar). It appears the plan, but no mark on it, so it's quite difficult to find where I placed it.

Thanks in advance, you team work and what you are creating it's great.
