To give a direct answer to your question, yes! See this thread. The problem is because a morph only moves vertices in straight lines, so a single morph can't emulate a rotation. Often the best solution is to divide the obj into multiple groups, and turn it into a figure, and use rotate channels to implement the bend.

As phantom3D said, there is also some discussion of this in the "Antonia - Opinions?" thread, but that thread is now so huge that it may be hard to find the relevant posts.
