Group by specific coulumn differentiating specific columns

Hello people,

I have a list such as:

Now I want a seperate table giving me the following result:
"name" grouped but still differenciated at "region" and "period". -> only summarized "subname" and summed the counts.

Thanks for you help! 🙂

Is this possible in PowerQuery? I would need to have both tables, the orignial and new one seperated.
