No option on this yet with the current version of the theme however it is possible through code customization and or through the use of a plugin as what some users have done. The theme is not encrypted and so it can be modified accordingly. It just depends on your coding skills or you can just hire a coder to implement it for you. AppThemes also have certified community partners
