Calendar monthly view with a lot of items per day


We have calendar view for management team where we reflect a lot of different activities and in one day there might be up to 20 events happening.

And in calendar MONTHLY view not all of them are shown. Some are hidden and you need to open them separately by clicking.
Not useful and not convenient for management. As they need to see the whole picture of the month and make decision.

Would be great to have this fixed or get an other similar solution on monthly view.
