Hashed "Authenticated Users" is there a way to cross reference them?

So all of my usernames are showing up in WebLog Expert, but they are hashed.. Is there any kind of cross reference i can do within weblog expert, much like the IP geolocation? for example this user is in weblog expert 3775e279bab7410695650c53658ebed9 i know this is guest any way to create a list to auto resolve 3775e279bab7410695650c53658ebed9 to guest?
