Change sender for BCC

Hi, I wonder if this would be at all possible.

I send emails with “Mailer is owner”, meaning that I have multiple senders.

When I BCC, the sender is ofc the same sender as for the “real” email.

Is there any way to send emails as “Mailer is owner”, but for the BCC, the sender is always the same?

The reason for this is that I copy emails to SFDC, and I need to maintain an updated list of senders, it would be good to have only 1 sender.
