Build a Data Studio with multiple data sources with a control filtering

Hi,

Please write "I love DataStudio" at beginning of your bid to be considered for this project.

I wanna to create a simple datastudio report that will include 3 csv datasources and able to filter the datasource by a dropdown filter: 7 days, 14 days, and 31 days.

Included are 3 samples csv file and you can follow the template provided in the attachment files.


More details are provided in the images

The reason I am doing this is because we have a hard time with the FB ads report csv export. We can't calculate dynamic total reach of a specific time range. If you have a solution to calculate Total Frequency or Total Reach, please work with me on this project.
