Link note with calendar event

Hi, I saw this in some closed conversation here. Would it be possible to link eM Client’s notes with specific calendar events as I am aware it is not possible to edit event with different organizer?

I just want to note down the agenda points (for personal use only) to the event but I cannot edit the event itself directly. So I was just thinking to create a note in eM Client and link this note to the event.

Or is there any existing solution yet, please?
