Accrual balance report/ how to use months in column and years in rows

I'm building an OTBI report to based on Accrual Real time subject area, with the goal of displaying accrual balances.

To have a report that makes sense I used Pivot Table as a View mode instead of table.

As you can see I moved in columns the Accrual Type and the Month. At the same time in rows I'm also using Calendar Year which is prompted. The issue is here:

When the user filters the report for multiple years; the year is also displayed in the Month columns.

We would like to keep in column only the calendar name of the month; and have the year in row.
