It seems obvious that it cannot because B starts then A ends. Specifying Transition(B, A) would jump from A to B, transition B to A, then jump to B.

However you may want to specify the start and end independent of the clip start/end. For example you may want to start the A->B transition a few seconds after the B starts, and/or end it before the end of A so you can align, and then specify the start/end of transition.
