The same or similar morph inject/remove system v3 has but with a different library system. If M3's pose libraries end up like v3's my entire pose directory will be inject/remove poses. (And no, I won't use P5 to fix it) "Muscle tense" morphs. Like, when he's inactive his muscles are relaxed. But when he picks up something heavy, the the muscles in the related parts can be made to tense up via a morph dial. Hand, forearm and shoulder, etc.
