Another solution is to load your model twice - hide one of the animated models permanently. Animate your visible model normally. When you want to blend an animation animate your hidden model with the desired sequence and then, between the UpdateWorld and Flip commands, set the positions and rotations of the joints in your visible model to those of your hidden model - only the limbs you want of course !
Animation occurs at the UpdateWorld command so you can overide animation by manually positioning/rotating joints between The UpdateWorld command and the Flip command.
