Possibility to add Contact Information to Calendar

i am only interesting, is there any chance, if i add a calendar entry, is there a chance to take from contacts Informations? (Name, Adress etc.)

Can you explain more what you want? Contacts data is currently used in Calendar:

  • for location suggestions
  • for attendee suggestions

Okay i try to explain:
I want to use Nextcloud for a company calendar, add a date for a client meeting. And i will have all client Information/Contact in the Contacts App.
And if it is possible, i want to take the client adress/client name direct from the contact app.

So that should already be the case if I remember correctly.
