Need new function to automatic sync files to offline on ms Teams application on IOS

Hi

Im in need for an function to automatically synchronize files to offline on Teams application on Ipad iOS.

And when connected to wifi/cellular again, they will update if any change has been done for the files

I now there's a function to click on every each file to go offline. But the problem is when there's 250 different drawings and docs. It takes some hours to do that. 

Please have an update on the application to make this happen
