Groupy by 2 times on same field

Is there a possibily within the ui to group by 2 times on the same column?
I want to do this on the date field.

This way i could create a pivot table that groups per weekday and within the day by hour.

Hi @cobalt
Currently it's not possible to group by the same column multiple times:

You would have to return the column multiple times (with different names), either via SQL or a View.
