Hide senders email address in list view // Highlight subject line

I get emails from the same sender, I would like to hide the senders email address. so that there is only the subject line left. I tried to add the sender as a contact, and set it to appear as "  " but that didnt help.

To my knowledge, you can’t do this.  You can hide the senders email address (menu/tools/settings/mail/read and uncheck “Show email address in header”), but the name will still appear.
