No option on these yet with the current version of the theme and will require code customization to implement. The theme is not encrypted and so it can definitely be modified according to your requirements. Implementation just depends on your coding skills or you can just hire a coder to do it for you. Appthemes also have certified community partners
http://www.appthemes.com/partners/ that can be contacted for customization jobs.
Likewise, this feature has already been requested at the Ideas Exchange page
http://ideas.appthemes.com/jobroller/?orderby=votes of which implementation depends upon the numbers of users voting for it.
