Calculations over Custom Year

Hello:

I have a dataset with columns (Fiscal Year, Fiscal Quarter, Calendar Year, Calendar Quarter, Sales, Indicator) - Sample data attached. 

For each Indicator (eg. "xx") and user choice of Year & Quarter (Q1/Q2/Q3/Q4), I would like to sum up 4 quarters (starting with the user choice of year and quarter) and find the average quarterly sales  as output for each custom year.

I came up with the following but it is not working in all situations such as for eg. if the user selects Oct-Dec quarter of 2021, then the sum would be of the Oct-Dec 2021, Jan-Mar 2022, Apr-Jun 2022 and Jul-Sep 2022 quarters i.e. when the calculation involves quarters spread over two consecutive years. 

VAR __Quarter = SELECTEDVALUE('Quarter'[Quarter])
VAR __Year = SELECTEDVALUE('Year'[Year])

VAR __Result =
SUMX(
FILTER(
'Data',
YEAR('Data'[Date]) = __Year &&
'Data'[Quarter] >= __Quarter &&
'Data'[Quarter] <= __Quarter + 3
),
'Data'[Value]
)

RETURN
__Result

I am not sure if what I am attempting to do is possible within Power BI.  Any guidance would be much appreciated. Thanks in advance.
