EDATE AND SUMX doesn't work

Hi everybody

I am using the following measure to add the result of the calculation of a measure in several non-consecutive months:

SUMX(Dates,'Measures'[Measure])

This works perfectly. For example, when selecting 3 non-consecutive months ('01-01-2022', '02-01-2022',
05-01-2022) is adding the results given by the measure for each month.

But now I need it to show me the same sum, but for the equivalent of the months 1 year ago or 2 years ago.

For example, if I select ('01-01-2022', '02-01-2022','05-01-2022'), I would like you to add the result of the measurement calculated for '01-01-2021', '02-01-2021','05-01-2021'. For that I am using this measure:

SUMX(FILTER(Date,Date[Date]=EDATE((Date[Date]),-12)),'Measures'[Measure])

The problem with using functions like dateadd or parallelperiod is that they don't work with non-consecutive dates.

I would be very grateful to anyone who could help me.
