Switching a subtask to a main task?

CallmeQ

Is there a way to switch a subtask to a main task?  Projects have the same annual processes that need to be tracked but i want to display the current year as the main task and drop the previous year to a subtask.  Is there any way to do that?  And, is there any way to automate that? 

Thank you in advance!
