For Earth-Prime counterparts, I suggest doing as such:

John Diggle (Prime), rather than (Earth-Prime). Alongside this, for characters in the new Multiverse, such as Stargirl of Earth-2, I believe it should be listed as Courtney Whitmore (Earth-2P), as the 2P would stand for Earth-2, Prime, as the current Earth-2 and former Earth-2 are two separate universes. And Earth-96 Clark Kent should be listed as Deceased and replaced with the Earth-96P Clark Kent.
