Centering slide in carousel mode?

When I use carousel mode, the first slide appears flush left and then the next slide is right next to it. This is creating a look of two slides side by side, which I do not prefer. It divides attention between the slides and I would like for one slide to have precedence but also have the carousel effect.

What I would prefer is to have the current slide in the center, BUT also see parts of the previous slide to the left and part of the next slide to the right of the centered slide. I understand that would mean that the first slide would have nothing to the left of it (unless the last slide could be attached there) and the last slide would have nothing to the right of it (unless the first slide could be attached there and the carousel move smoothly instead of rewinding to the beginning.

When I try the non-carousel slideshow centered, there is too much blank space on either side of the slideshow. It would be best to have a carousel slideshow that has the currently active slide centered in the carousel instead of flush left.
