periodToDateSumOverTime where fiscal year different to an actual year

I was using periodtodatesumover function so far to calculate the YTD sum on a monthly basis. The report was working fine but today I was given a task to duplicate the report for a company which has a fiscal year from march to march. And I do not know how to approach this. Any suggestions?

The problem is that there is no way to pick different granularities than those defined. periodToDateSumOverTime - Amazon QuickSight

periodToDateSumOverTime(sum({measure_forecast}), {snp_date}, PERIOD)

To visualize, please find tables below

Here is okay
