simplyplural, pluralkit and anything you use to log fronting, differentiate alters and overall create more amnesia and difficulty in therapy is anti-recovery. if you're actually interested in final fusion and recovering from this disability, you would not want to make it harder to fuse by making each part more distinct than they may already be. remember, there is no dissociative identity in DID if you're acting like they're all different people; they're just fragmented and dissociated parts of YOU as a result of the trauma you went through in childhood.
you also cannot FORCE someone to have a system, that is not how the brain works
