Can a Deck Card simply be connected to a contact?

Maybe I am doing something wrong, but is it not possible to link a deck card to one or more contacts? Not as owner... just as a connection/link if the activity is linked to a customer i.e. , and I may/would create all customers i a contact group, named "customers".

And vice versa in the contacts ... a list of all objects they are linked to: :-)

Best regards.

No files, tests, or entry points are named.

Review the existing card and contact integration before defining acceptance criteria for both directions.
