Year end store number should be equal to fourth qurter of the same year.

[Myura]

I have following table.

Date	Segment	Quarter	No of stores	No of sales
31/12/2017	America	Q1	100	45216
31/03/2017	America	Q2	200	6589
30/06/2017	America	Q3	300	2388
30/09/2017	America	Q4	500	6358

I want to display year end figures in the pivot table. I have created a measure for total sale. I want to display year end stores number too. How can I create a measure which displays Q4 number for the filtered year, and the segment.

Thanks in advance.
