Retrieve process instances + variables

Hey everyone :slight_smile:
Is it possible to save a historic process instance with its variables form cockpit? I need to save some finished process instances and their variables. The problem is, some variables are objects. Until now I managed to save the process instances in a csv file but with no variables. any help is much appreciated :slight_smile:
