Fiscal Year Descending Sort

Hi, I am having a challenge in my Pivot Dashboards where my users would like to see the current fiscal year first and the the next years 

I am using Fiscal Year as the Column for my Dashboard (we are on V15 if that matters)  I am still new to Tessitura and have spent a few hours fumbling over this one if someone could point me in the right direction or offer me a solution. Thank you.
