Also there may be an option to customize this in the Pro version but I have no idea of verifying this nor do I work for them.
In order to do this you will have to feel comfortable going into the files and editing the CSS code in the main.css (note if you ever upgrade the template it may overwrite this and you would have to do it again).
In your site files go to:
wp-content > themes > sixteen > css > main.css
at line 101 you will find:
text-align: center;
change this to:
text-align: right;
Hope that helps!
In the dashboard menu go to Appearance > Sixteen Settings and you should find a tab for Slider Settings.
