Import Dynamic CSV files based on input date from the NAS folder

Thanks for sharing the detailed steps.
I could be able to do it in the Power BI Desktop, it is loading the file based on the date parameter but i can't find the input the date, once it is published to "Power BI Service". Will it be feasible to do it in Power BI Desktop?

As a beginner,it might be a basic question that I want something like based on the end user input date selection from the Power BI Service, it has to load the respective file from the source location.  eg: Let's say in the below screen shot, if the end user selects a value from the dropdown then click on "view Report" then it has to load the respective file

Really appreciate your help.

Thanks
