Adding Animations to single model

By searching on Oinkerwinkle's http://www.oinkerwinkle.com/tools/index.html
I've learned to replace existing animations.

How can I ADD new animations?
Is it possible to put NEW (self-made) Animations into single original-Warcraft model?

Please help me :y-sad: :y-sad:

hmm, ya it is possible but you need max or note track.
