Custom report - Totals per tag and year

I tried to make a copy of the Incomes and Expenses per year report and tried to replace the categories by the tags.
The documentation about the 5.0 release show in the section Configuring Reports / Rows/Columns Subtab, the possiblity to select one or the other colums.
I use KKM 5.1.2 on Ubuntu 22.04.3 LTS
Thanks in advance for your help
