Azure data lake dynamic files picking automatically

Hi all 

My source is azure data lake gen2 

I have one folder in data lake in that folder files like this week 1 data

Week 2 data

Week 3 data

 

Every Friday one new file updated  in the same folder

I was already implemented  report based on week1 data

But I need for the same report  week 2 and week 3 etc 

 

And also I need one weeks filters in dashboard 

Once user selects particular week number  automatically that total report and tables we want showing the corresponding week data only.
