File size impact of duplicated animations

Putting the notifies on one animation would necessitate a lot of rework. It isn’t just that specific case (that’s just an example), it’s things like

-charged up melee attack release has 3 levels, based on charge
-each one is the same animation but with a slightly faster play rate and slightly altered parameters on the hitbox animnotify

They’re all imported from the same .fbx file. Still it sounds like UE treats every imported animation as its own standalone entity, which is what I was curious about.
