in Odoo 16, When creating a new record in “Incoming Mail Servers” (a Gmail account for example), a message is created on the system(mail.message model) as soon as a new message arrives, and the recipients of this message are specified in the “partner_ids” field, and the message is displayed on the third page of the notebook in Form View. for the message,

The "partner_ids" field includes the recipients to whom the original message was sent through Gmail, and they are (to, cc) and they are combined together in this field(partner_ids). What I want is to specify "to" in a separate field, and specify "cc" in a separate field.

I have searched this issue a lot and have not found a solution. Can anyone help?
