Filtering a ranked table by a month slicer

Hiya all,

I have a ranked table which ranks the SKUs in a group by their sales :

A. Table for ranking

SKU Rank = 
groupby('Amazon YTD','Amazon YTD'[Title],
"Sales value",
SUMX(CURRENTGROUP(),
'Amazon YTD'[Item Price])
)

B. The code for the rank column :

Rank = 
RANKX(all('SKU Rank'),
    'SKU Rank'[Sales value],,DESC,Dense
)

I have a visual (screenshot below) , wherein I want to show the top 3 SKUs by month, if I add the months as a filter on the visual :

the visual with the rank table

The problem is the rank table does not change if I change the month - because the SKUs are ranked on the SKU rank table.

Is there a way I can slice this rank table by month - which means the top 3 SKUs will change to show the rank of the SKUs within the month chosen?
