Calendar / Searching for Contacts to set location

Hello everybody,
I’ve made the switch from Google Calendar and Contacts to my Nextcloud. My calendar entries are correctly synchronized with my mobile systems.
When I enter new appointments in my calendar, it would be a great relief if I could automatically search for the addresses in my contacts for the location of the appointment and then adopt them.
Then I would have another added value to maintain my contacts.

I mean that this is currently not possible in the calendar app.
