Premiere Elements 15 - Iris Transition

Just starting to play with this program using one clip. I put an iris transition at the beginning of the clip and, as expected, it's like an iris opening up - initially everything is black and the clip is shown in an increasingly larger circle until everything is revealed.

I am trying now to figure out how to put an iris closing transition at the end of the clip. If I put the same transition at the end of the clip, no matter what options I choose, all I get is a black circle that keeps increasing until everything is black (because there is no clip after the one I'm using). Isn't there a way to do the opposite - gradually blacken the video as if an iris were closing?

Thanks.
