Hi, we are starting to use the Email Marketing App in Odoo 16 and is a bit surprised that there doesnt seem to be a relation to Customer Contacts. 

For instance in my opinion it would make sense that you could direcly sign op a Customer Contact to an existing Mailing List directly from the Customer Contact form? Or, from the Mailing List Contact view, to assign directly an existing Customer Contact to that mailing list?

If none of my above mentioned assumptions/suggestions is possible it would mean that there is no relation between Mailing Lists Contacts and other contacts (ie. Customer Contacts) in Odoo meening that the same contact potentially would have to exist in multiple places in Odoo?

Can this be true?
