S3D v0.9.4 features a copy-paste function. In your case all you have to do (if I understand you correctly) is copy the animation node and all of its contents (KeyFrameAnimStartParams, PositionKeyFrames and RotationKeyFrames).
to do this select one of these properties, press the copy button and the paste button. Now you've got a duplicate. Repeat this for each one, change the parent ID and index of them, and you're finished.
