It doesn't provide a way to do it at the moment.
But you probably can do it with CSS very easily:

#pp-nav{
    margin: 0 auto !important;
    left:0;
    right: 0;
    top: auto !important;
    bottom: 17px;
    display: inline-block;
}
#pp-nav li, .pp-slidesNav li{
    display:inline-block;
}

Then you would also need to deal with the tooltip, if you are using them, but I have no time for that now.

is there a way to have the dot on 2 places? I was a set of the dots on the left and right side of the page

The plugin doesn't provide such an option I'm afraid.
