I would try the following

1. make a key frame for the body one frame before your walk animation.
2. after importing the figure, move the body to the right position so that the figure is at the right place again.
3. end with a key frame for the body and start the rest with a new key frame after moving the body back.

Haven't tried this, but I think this should work. If the body actor changes, you may need to parent the figure to an invisible prop you can use to move the figure without changing the body dials.

Does this help?
