Pivot table , Date hierarchy

Hi,
I would like to show the folliwing in a piovt table


2020 Nov / Dec

2021 Jan / Feb

so using filter ;

FILTER(F4:G51, (( F4:F51 >=I10)*(F4:F51 <J10)) +((F4:F51 >I11)*(F4:F51 <J11)) )

I have tried using advanced filter also but not sure about how, but my main is the pivot, I have attached the above and a pivot with
a date hierarchy showing the dates required but it is also show all the other months I don't want to see, help?
