QUARTELY COHORT ANALYSIS?

[Andrew_na_lang]

I have a cohort analysis which is typically montly. 

My boss wants it quarterly. 
I created calculated column to group our customers : 

(DATE) ORDER QUARTER & YEAR =

VAR _FirstOrderDate = CALCULATE(
MIN(orders[time_dropoff_id]),
FILTER(
ALL(orders),
orders[customer_id] = EARLIER(orders[customer_id]) &&
NOT orders[order_status_code] IN {7, 10, 2.5}
)
)
VAR _Year = YEAR(_FirstOrderDate)
VAR _Quarter = QUARTER(_FirstOrderDate)
VAR _MonthEndOfQuarter = _Quarter * 3
VAR _LastDayOfQuarter = EOMONTH(DATE(_Year, _MonthEndOfQuarter, 1), 0)
RETURN _LastDayOfQuarter

I created series that will serve as my column 

Quarter_After = GENERATESERIES( 0, 1000, 1 )


I need DAX where I want know how many from cohort  0 is left quarter by quarter similar to my monthly cohort :

 My monthly cohort retention dax is like this: 

Current Retention Value =

VAR currentMonthsAfter = SELECTEDVALUE('Months after'[Value])

VAR currentfirstordermonth = SELECTEDVALUE( orders[(DATE) FirstOrderMonthYear])

RETURN

    CALCULATE(

        DISTINCTCOUNT( orders[customer_id] ),

        FILTER(

            orders ,

            EOMONTH( orders[time_dropoff_id].[Date] , 0 ) = EOMONTH( currentfirstordermonth , currentMonthsAfter )))

Hi @Andrew_na_lang ,

Can you please share a pbix or some dummy data that keep the raw data structure with expected results? It should help us clarify your scenario and test to coding formula.
