Email sender name

I’ve got several email accounts set up, including a few group email addresses (sales, service, etc.)

From the interface, my Frappe system users are able to select which one they want to send from when sending emails, but the sender name is always set to their Frappe Account first name + last name?

Is this intended behavior? I’d like emails sent from the Sales account to just say “Sales” instead of listing the individual who sent its name. Is this possible?

Any tips on this, even just whether or not it is expected behavior?

Any ideas here? I’ve been trying to dig through the code, but I’m having a hard time understanding how the email backend is configured.
