as far as I know currently there is no way you can do this. You can go from PS3 to PS4 but not PS4 to PS3 or PS4 to PC or PS3 to PC. I to would like a way to easily go between systems and not have to redo every single hotbar for every single class and job and if they could impliment something like they have on FFXI where it saves 1 character macro and configuration data server side for you to use anywhere it would be rather useful.
