How to display last 6 quarter data?

Hi Team,

Right now, my report pulls in the data for current year and previous year as shown below. I would require my report to display only the last 6 quarter at any point of time. For example, If the current month is Jan 2016. Then my report should display, Q1 of 2016, Q4 2015, Q3 2015, Q2 2015, Q1 2015 and also Q4 2014 which would be the last 6 quarters. Could you please help me achieve this?

Thanks,

Sid
