How to create weekly timeline in x-axis with rolling average slicers by months?

Hello happy new year!
I currently have date/timeframe hierarchy setup in year/quarter/month with rolling average slicer (by month in 1, 3, 6, 12). I was trying to add another level as 'first day of the week' in timeline (eg. year/quarter/month/1st day of the week) but struggle to have it works with the currently rolling average slicer.

Any helps are highly appreciated.

Thanks!
