Link event to note

Is your feature request related to a problem? Please describe.
Most of the events in my calendar require some written preparation and documentation. If I put those texts in the description fields of the events, I have to go through all events that belong together to get an overview of them. That can get frustrating when a lot of events belong together (like lectures or lessons).

Describe the solution you'd like
I'd like to create a link from a calendar entry to an existing note or create a new note when adding an entry to a calendar.

Describe alternatives you've considered
I guess it's possible to create a note and paste it's url into the description field. But copying and pasting urls isn't comfortable, especially when working on mobile devices.

Additional context
Unfortunately I'm no programmer, but if I can help with a more precise description or something similar, please let me know.

Thanks for your great work!

The issue names no files, tests, or entry points. First clarify how calendar events should link to existing notes and how new notes should be created, then trace the event creation and editing flows and define the expected behavior across supported clients before implementation.
