Overriding properties within Morgen for external events

One thing I actually wish for is actually being able to have some sort of "Morgen-Override" for events.

Let's explain it for myself:

I connected my work calendar with Morgen. But only as read only as my employer does not allow me full permissions for the calendar.

That leads to the issue that I can't change anything about events that I put it that calendar.

Or if someone else created it and I got invited (e.g. dailies).

In the end I'd appreciate if I could do changes on Morgen for myself.

I use Notion with everything. I personally would like to put a certain Notion page as a link for my dailies because I do my protocols and notes in Notion.

I can do that with my own, private calendars (as a location). Not with my external calendars.
