To do it from one step onwards, on the other hand, the easiest way is probably to use a submodel. For example, if the part is added in step 10, and then rotated a different way from step 20 onwards, you could put the buffer exchange store command right before the part in step 10 (as described above), then build through step 19. At that point you'd make a submodel copying all the parts added from steps 11-19. Then add step 20, insert the buffer retrieve command (everything after step 10 disappears), and then add the submodel plus the part in its new rotated position.
To me this is the biggest drawback with buffer exchange, the need to add multiple instances of parts that only occur once in the actual model. (I've envisioned a new meta called FLOAT that would not have this problem, but unfortunately I haven't the skills to make it anything more than a vision.) :-)
