Hi 

I have following case:

Person X is a customer in our shop. Her husband person A is a contact of her (so he gets also access to the website through portal access). 

Now person A also has a company. He also wants to be a contact of that "customer" in our system. So he can login with the same mailadres to see the 2 entities. 

First of all how can i do this? In odoo 15 i only have the option to add a new contact under a contact not an existing contact (which gives already problems with the mailaddress that has to be unique)

Thanks for your insights!
