Can you add unique animations to custom followers with CK?

Also, how do I add new combat voices for my custom follower? (not dialogue, because I don't have voice actors) I've been looking around for a guide specific for combat voices. The thing is, I want my just my follower (not other NPCs) to have different combat voice by using a sound files from a voice mod I downloaded.

As long as you create a subrace for that companion I guess you could add a new behavior for that race using your "unique" animations. You need to create a new folder under meshes\actors\MyCustomRace\, then go to skyrim - Animations.bsa, look for the folder meshes\actors\character and extract everything inside the folder you created previously. After that overwritte the animations you want, make your follower use the custom race, and he will be the only one to play those animations.
