Feature Request - Changing names per DM

It would be great if we could change our username per DM the way we currently can do in individual servers. The reason for this being that we often use different names with different social groups, but shouldn't need to have multiple Discord sign-ins to do so. I would love to use Discord via DMs with an employer under my real name, my father under his pet name for me, my best friend from high school with the old nickname she knows me by, and my online social group with a username they know me from elsewhere. Right now, there is no way to set this.
