How to calculate rolling sum within a calendar year

At the moment, rollingWindow leading and trailing parameters supports values in the following format: (-?\d+) (minute|hour|day|week|month|year) which can be used to define the window size to the right and left of the offset.

I need to calculate the accumulated sum of parameter (income_per_mth) within a year, i.e. start calculating the accumulated parameter again with the onset of January of the following year. The granularity of the data is the month.

I tried to formulate this logic as follows:

```javascript
accum_param : {
title: 'accum_param_year',
sql: `income_per_mth`,
type: `sum`,
rolling_window: {
offset: 'end',
trailing: '1 year'
},
}
```
But it doest start over the calculation in January of the next year. It works with a granularity of a month, i.e.
it counts the accumulated parameter within 12 months, and not within a certain year. For example, for March 2024, the calculation will start from March 2023, but I need it to start from January 2024.

Please suggest how I can solve my problem.
