Hello Marianna,
You can find some examples how such rolling reports can be created in the default column definitions that ship with the MR.
I added you some screenprints for your reference
With such a setup you don't have to change the column definition configuration every year.
The only thing required is running the report for the current period; the rest is calculated by MR.
Best regards,
Ludwig
P.S. Some additional information on report creation can be found for example on youtube. Have a look at the videos available there.
