StepCarousel Wrap backward only

[SPT]

1) Script Title: stepcarousel.js

2) Script URL (on DD):http://www.dynamicdrive.com/dynamicindex4/stepcarousel.htm

Is there anyway to setup stepcarousel.js to wrap back to the first slide after reaching the last slide and NOT have the first slide wrap forward to the last slide?

So the wrapping action would only take place when the last slide is reached.

Thanks
