Monthly view: Decide which tasks to be displayed in task preview

It would be great if we could pin one icon or task to the monthly overview for each day so that we can see at a glance what’s coming up that’s important. With the current way all icons are visible it’s impossible to see if there is anything important coming up. For example I could pin ‘mums birthday’ or a birthday cake symbol only so I know something really important is happening. At the moment you have to go into the day directly to see what’s happening. For someone like me who forgets plans I’d like to be able to open monthly overview and see that in two weeks I’m meeting friends for example. I still have to rely on my calendar app for this but I would prefer to just use structured to do all of this.
