Career Mode: Changing “Known As” Name

We should be able to change the “known as” field for our player after s/he is created in career mode. I didn’t know that what I put in the “known as” field would appear everywhere. I thought that was a nickname that was saved but my actual players name would show everywhere (team sheet, profile, social media feed etc.) Even if that is a nickname, people change their nicknames all the time, so it should be editable.
